PowerManager
General Description
Features
The AAT351x PowerManager™ products are
members of AnalogicTech™'s Total Power
Management IC™ product family. This family of
Microprocessor Reset Circuits provides the ulti-
mate 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 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

Note 1: Over-temperature limits are guaranteed by design, not production tested.
Note 2: This is the minimum time RESET must be held low by an external pulldown source to set the active pullup flip-flop.
Note 3: Measured from RESET VOL to (0.8 x VCC), Open Circuit Output.
Note 4: Watchdog timeout period C is not available on AAT3513, AAT3514, and AAT3518.
Note 5: WDI is internally serviced within the watchdog period if WDI is left unconnected.
Note 6: 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.
