DATA SHEET AAT3510/3515/3517/3518 Micropower µP Reset with Watchdog Timer General Description Features The AAT351x PowerManager products are members of Skyworks' Total Power Management IC (TPMIC™) product family. This family of microprocessor reset circuits provides the ultimate in versatility, allowing system designers full customization 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 period, and output drive configurations, which are all factory-programmed options. All devices are available 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 ▪ Bi-Directional • Low Temperature Coefficient: 100ppm/°C • 5-Pin SOT23 Package The AAT351x family is designed to ignore fast negative transients on VDD and to ensure that reset outputs remain valid down to 1V. Applications The AAT351x family is available in the Pb-free, spacesaving 5-pin SOT23 surface mount package and is specified over the -40 to +85°C temperature range. • Critical µP and µC Supply Monitoring • Embedded Control Systems • Industrial Controllers • Intelligent Instruments • Notebook Computers • Portable Electronics • Power-On Reset Circuits Typical Application V DD VDD VCC RESET (RESET) RESET INPUT µP AAT351x WDI I/O LINE GND Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • sales@skyworksinc.com • www.skyworksinc.com 202243A • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice. • August 8, 2012 1 DATA SHEET AAT3510/3515/3517/3518 Micropower µP Reset with Watchdog Timer Pin Descriptions Pin Number AAT3510 AAT3517 AAT3515 AAT3518 Symbol 1 1 1 RESET 2 2 2 GND N/A 3 3 RESET 3 4 N/A MR 4 N/A 4 WDI 5 5 5 VCC Function AAT3510/15: RESET output goes low whenever VDD falls below the reset threshold.
