GENERAL DESCRIPTION
Low Current Consumption
(3µA typ., VDD =3V)
High-Precision Reset Voltage Accuracy
±2%(A/B), ±1%(C/D)
Hysteresis Voltage 5% Typical
Reset Voltage 1.8V to 5.5V
Fixed or Adjustable Delay Time
Open Drain or Push-Pull Output
External Delay Time
SC82AB9(SOT343), SOT23-3, SOT23-5,
The AAT600 is a high-precision reset voltage detector. It
provides a high-precision output signal, which allows
users to initiate or reset the system.
The detection voltage with an accuracy of ±2%(A/B),
±1% (C/D) is trimmed to customer’s specification. Delay
time can be adjusted by an external capacitor. The
output signal may be configured as either open drain or
push-pull. With minimal external components, the
AAT600 offers a simple and economical solution.
