MPQ2946 and MPQ86760

MPQ2946 multi-phase controller and MPQ86760 Intelli-Phase™ Solution

MPQ2946 is a digital, three-rail, multi-phase controller for autonomous driving applications. It can work with MPS’s Intelli-Phase™ products to complete the multi-phase voltage regulator (VR) solution with minimal external components. The device can be configured for up to 8 phases between three rails.
The on-chip, multiple-time programmable (MTP) memory stores and restores device configurations. Device configurations and fault parameters can be configured or monitored via the digital interface. The MPQ2946 can monitor and report the output current (IOUT) through the Intelli-Phase™ current-sense (CS) output.
The MPQ2946 is based on unique, digital, multi-phase nonlinear control to provide fast transient response to a load step with minimal output capacitors. With only one power loop control method for both the steady state and load transient response, power loop compensation is simple to configure.
The MPQ2946 is available in a TQFN-48 (7mmx7mm) package. It is available in AEC-Q100 Grade 1.

MPQ86760 is a monolithic half-bridge with built-in internal power MOSFETs and gate drivers. It can achieve up to 45A of continuous output current (IOUT) across a wide input voltage (VIN) range.
The integrated MOSFETs and drivers achieve high efficiency through an optimized dead time (DT) and reduced parasitic inductance.
The MPQ86760 is compatible with tri-state output controllers. It also includes general-purpose current sensing and temperature sensing.
The MPQ86760 is ideal for autonomous driving applications where efficiency and compact size are at a premium. It is available in a TQFN-21 (4mmx5mm) package.
