A4811A
SUPERVISOR (RESET IC) LOW VOLTAGE DETECTOR WITH BUILT-IN DELAY CIRCUIT
DESCRIPTION
FEATURES
A4811A is a series of high precision voltage detector with ultra-low current consumption (4.5uA typ. at Vin = 3.0V) and a built-in delay circuit. It can work at very low voltage, which makes it perfect for system reset. A4811A is composed of high precision voltage reference, comparator, delay circuit, output driver and resistor array. Internally preset detect voltage has a low temperature drift and requires no external trimming. Only CMOS type is available.
High-Precision Detection Voltage: ±3% Detection Voltage: 2.63V and 2.93V Built-in Power on Reset Delay Time circuit:
Refer to Selection Guide Operating Voltage Range: 1.2V~6.
