TC1271ATVCTTR

The TC1271A family are cost-effective voltage supervisor devices designed to keep a microcontroller in Reset until the system voltage has reached and stabilized at the proper level for reliable system operation. These devices also operate as protection from brown-out conditions when the system supply voltage drops below a safe operating level. A Manual Reset input (MR pin) is provided. This allows a push button switch to be directly connected to the TC127XA device, and is suitable for use as a push button Reset. This allows the system to easily be reset from the external control of the push button switch. No external components are required. The Reset pin (RST or RST) will be forced active, if any of the following occur: During device power-up VDD goes below the device threshold voltage The Manual Reset input (MR) goes low.
