Maxim MAX77714 and MAX77752 evaluation boards

Powering the industry's top CPUs, GPUs, APUs, gaming processors

MAXIM’s feature-rich, high-performance, and scalable power-management ICs (PMICs), designers of mobile systems can now maximize performance per watt while increasing system efficiency for computationally intensive deep-learning systems on chip (SoCs), FPGAs and application processors.

The MAX77714 and MAX77752 address a broad spectrum of applications ranging from reality/virtual reality (AR/VR), gaming, SSDs, security and industrial internet of things (IoT) to handheld devices such as cameras and home automation hubs. Architected to deliver numerous benefits, including consuming 40 percent less power than standard solutions, the PMICs extend battery life while providing the most compact form factor in the market.


High-performance PMIC for computationally intensive applications

The MAX77714 PMIC delivers a complete, efficient power-management solution in a compact package to enable multi-core processor-based systems to operate at maximum performance with greater than 90 percent efficiency at 3.6VIN, 1.1V OUT. With a 70-bump, 4.1mm x 3.25mm x 0.7mm WLP package, it enables thinner, smaller devices and extends battery life up to 40 percent compared to stand-alone solutions. It reduces design cycle time, component count, and bill of material (BOM) costs compared to discrete solutions by integrating 13 regulators, including 9 low dropout linear regulators, real-time clock (RTC), backup battery charger, watchdog timer, flexible power sequencing and 8 general-purpose input/outputs (GPIOs).

High-performance, compact multi-channel PMIC with hot-plugging capabilities

The MAX77752 is a multi-channel, compact and integrated power management IC (PMIC) designed for applications with multiple power rails and hot-plugging capabilities. It improves efficiency up to 90 percent at 3.6VIN 1.8VOUT for longer battery life and includes a flexible power sequencer (FPS) to allow hardware- or software-controlled power up. It reduces design cycle time, component count and BOM costs by integrating three buck regulators (with high-accuracy brownout comparators), one low dropout linear regulator, two dedicated load switch controllers, one in-rush current limiter, two external regulators to enable outputs, voltage monitor for backup power control and a dedicated digital output resource for logic control. The MAX77752 comes in a compact 40-pin, 5mm x 5mm x 0.8mm 0.4mm-pitch TQFN package.

Game changing power management solutions powering wearables, hearables and Low Power IoT devices

Portable devices in the consumer market, especially those in the field of Hearables, Wearables and internet of things (IoT) space, all share the same challenge: they are highly constrained on size - visualize your ears narrow canal or lifestyle solutions that need to be sleek & fashionable. All these devices need to have a long battery life.

The consumer market is on an incessant mission of increasing performance, yet solutions are expected to reduce power consumption and further extend battery life. At the heart of this are the power management integrated circuits, or PMICs, that govern power distribution from the battery to the rest of the system. PMICs are critical in solutions with ultra-low current restriction as they determine how much current is drawn from the battery at light loads or in shutdown. Therefore, when evaluating PMICs, shutdown and quiescent current should be considered along with power capability and efficiency.

In addition to having ultra-low current draw, PMICs integrate features to optimize battery charge-discharge cycles. For example, the PMIC may keep the battery topped off at its peak voltage, so maximum battery capacity is available. And, during discharge, a PMIC may enable operation down to the lowest possible state-of-charge, extending the device’s operation time.

Besides battery management, PMICs can offer other features that help reduce design time. For example, Maxim offers PMICs not only with ultra-low current draw and JEITA standard battery charging, but I2C control, GPIOs, and current sinks for LEDs. The default behavior of these parts is factory programmable, so parts can arrive at engineers’ desks already fine-tuned for their specific applications.


Ultra-Low Power PMIC, 3-Output SIMO & Charger

The MAX77650/MAX77651 provide highly-integrated battery charging and power supply solutions for low-power wearable applications where size and efficiency are critical. Both devices feature a SIMO buck-boost regulator that provides three independently programmable power rails from a single inductor to minimize total solution size. A 150mA LDO provides ripple rejection for audio and other noise-sensitive applications. A highly configurable linear charger supports a wide range of Li+ battery capacities and includes battery temperature monitoring for additional safety (JEITA).

The devices include other features such as current sinks for driving LED indicators and an analog multiplexer that switches several internal voltage and current signals to an external node for monitoring with an external ADC. A bidirectional I2C interface allows for configuring and checking the status of the devices. An internal on/off controller provides a controlled startup sequence for the regulators and provides supervisory functionality when the devices are on. Numerous factory programmable options allow the device to be tailored for many applications, enabling faster time to market.

Ultra-Low Power Tiny PMIC with Power Path Charger for Small Li+ and 150mA LDO

MAX77734 is a great example of a PMIC that handles battery charging and provides power to the system while drawing miniscule power for itself. In shutdown mode, this device draws only 500nA typically, and for long shelf life, the MAX77734 factory ship mode further reduces current draw to 200nA typically. The linear charger integrated in this device follows the JEITA standard to ensure safe charging and can charge batteries with a maximum of 300mA. To prepare the MAX77734 for future battery technology, the maximum charge voltage is 4.6V.

In addition to the battery charger, an LDO is available that can be enabled through firmware or through an on-key such as a slide switch or push-button. This part communicates to the host via I2C serial communication, an interrupt pin, and an AMUX pin. The interrupt pin ensures quick notification to the host about power-related problems, and the host can use the AMUX pin to monitor different analog signals, like a thermistor voltage or battery current. For visual indications, the MAX77734 drives two current sinks that can control LEDs.
