Product details

2.22V threshold supervisor for battery-backed rails

It holds the reset output for a minimum of 60ms after the rail recovers, giving the processor time to stabilise before release. The push-pull, totem-pole output drives the reset line directly without an external pull-up resistor.

What the 60ms timeout buys the BOM

A 60ms minimum reset timeout is long enough to cover most power-supply glitches and brown-out events without requiring an external delay capacitor. For a processor booting from flash, 60ms typically exceeds the oscillator start-up and PLL lock time, so the reset de-assertion happens after the core is ready to fetch instructions. If the downstream processor needs a longer hold time, an external RC on the reset line can stretch it further.

Frequently asked questions

What is the reset timeout for TPS3600D25PW?

The reset timeout is a minimum of 60ms. After the monitored voltage rises above the 2.22V threshold, the reset output stays low for at least 60ms before releasing.

Is TPS3600D25PW compatible with 3.3V systems?

Yes, the 2.22V threshold is appropriate for monitoring a 3.3V rail — it trips at roughly 67% of nominal, which is a typical brown-out detection point for 3.3V logic. The push-pull output also swings to the supply rail, so it interfaces directly with 3.3V processor reset inputs.

What is the difference between TPS3600D25PW and TPS3600D20PW?

The two parts differ in the voltage threshold: TPS3600D25PW monitors at 2.22V, while the TPS3600D20PW monitors at a different threshold (not specified in this listing). Both share the same 14-TSSOP package, active-low reset, push-pull output, and 60ms minimum reset timeout. The choice depends on the nominal voltage of the rail being supervised.
