™™

PoSwmearrMtSawnaitgcehr

General Description

Features

The AAT351x PowerManager products are mem-

bers of AnalogicTech's Total Power Management

IC™ (TPMIC™) product family. This family of

microprocessor reset circuits provides the ultimate

in versatility, allowing system designers full cus-

tomization of the µP monitor and reset function

without any additional components. The AAT351x

family offers several combinations of threshold

voltage, watchdog timeout period, reset active peri-

od, and output drive configurations, which are all

factory-programmed options. All devices are avail-

able in 32 reset threshold voltages from 2.6V up to

5V, with three watchdog timeout periods from

6.3ms to 1600ms and three reset timeouts from

1ms up to 140ms. Available output configurations

are active low push-pull, active low open drain,

active low bi-directional, and active high push-pull.

•

Tight Voltage Tolerance: ±1.5%

Low Quiescent Current: 5µA

Guaranteed Reset Valid Down to 1V

32 Voltage Options from 2.6V to 5.0V

Three Reset Active Period Options:

— 1ms, 20ms, 140ms

Three Watchdog Timeout Period Options:

— 6.3ms, 102ms, 1600ms

Four Output Options:

— Open Drain

— Inverting

— Non-Inverting

5-Pin SOT23 Package

The AAT351x family is designed to ignore fast neg-

ative transients on V_DDand to ensure that reset

outputs remain valid down to 1V.

1. Over-temperature limits are guaranteed by design, not production tested.

2. Watchdog timeout period C is not available on AAT3513, AAT3514, and AAT3518.

3. WDI is internally serviced within the watchdog period if WDI is left unconnected.

4. The WDI input current is specified as the average input current when the WDI input is driven high or low. The WDI input is designed

for a three-stated-output device with a 10µA maximum leakage current and capable of driving a maximum capacitive load of 200pF.

The three-state device must be able to source and sink at least 200µA when active.
