General Description

The APR3011/2/3 are designed to monitor voltage supplies in mP and digital systems. The quiescent current is extremely low, typically 1.5μA, making it ideal for portable battery operated equipment. The APR3011/2/3 operate by monitoring the system power supply voltage. When the input voltage drops below a fixed threshold, the device asserts a reset signal for a fixed time period after Vcc rises above the fixed threshold.
