1 / 11 page  SmartSwitch™ AAT3510/1/2/3/4/5/6/7/8/9 Micropower µP Reset with Watchdog Timer 3510.2006.03.1.7 1 General Description 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. The AAT351x family is designed to ignore fast neg- ative transients on V DD and to ensure that reset outputs remain valid down to 1V. The AAT351x family is available in the Pb-free, space-saving 5-pin SOT23 surface mount package and is specified over the -40 to +85°C temperature range. Features • 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 — Bi-Directional • Low Temperature Coefficient: 100ppm/°C • 5-Pin SOT23 Package Applications • Critical µP and µC Supply Monitoring • Embedded Control Systems • Industrial Controllers • Intelligent Instruments • Notebook Computers • Portable Electronics • Power-On Reset Circuits Typical Application AAT351x VCC RESET GND (RESET) RESET INPUT µP VDD V DD I/O LINE WDI PowerManager™ |
