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.

AAT3510/15: RESET output goes low whenever VDD falls below the
reset threshold. CMOS push-pull output.
AAT3517: RESET output goes low whenever VDD falls below the reset
threshold. Open drain output. Connect a pull-up resistor to any supply
voltage up to 5.5V.

threshold. Open drain output. Connect a pull-up resistor to any supply
voltage up to 5.5V.
Ground connection pin.
RESET active-high output. This CMOS push-pull signal is the logical
inverse of RESET.
Manual reset input pin. Active low. Pull low to force a reset.
Watchdog input pin. Triggers a reset if it remains in a steady state for
the duration of the watchdog timer period.

1. Over-temperature limits are guaranteed by design, not production tested.
2. Watchdog timeout period C is not available on 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.
