Product Summary
For many of today microcontroller applications, caremust be taken to prevent low-power conditions that can cause many different system problems. The most common causes are brown-out conditions, where the system supply drops below the operating level momentarily.
The second most common cause is when a slowly decaying power supply causes the microcontroller to begin executing instructions without sufficient voltage to sustain volatile memory (RAM), thus producing indeterminate results. The TC127XA family (TC1270A, TC1270AN, and TC1271A) 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
