Temperature range: –40°C to +125°C

Package: 1.5-mm × 1.5-mm WSON

The TPS3899 is a nano-Iq, precision voltage

supervisor that monitors system voltages or push-

button inputs as low as 0.51 V. When the voltage of

SENSE drops below the V_IT-threshold, RESET/

RESET will toggle after the programmed sense delay,

set by CTS, has been reached. The TPS3899 asserts

an open-drain or push-pull RESET/RESET signal to

active-low logic (RESET) or active-high logic (RESET).

The RESET/RESET output remains active until the

SENSE voltage returns above the rising voltage

threshold (V_IT-+ V_HYS) for the reset delay set by CTR.

The TPS3899 family uses a precision reference to

achieve ±1% threshold accuracy. The sense delay

and reset delay time can be user-adjusted by

connecting a capacitor to the CTS and CTR pins

respectively. The TPS3899 has a nano quiescent

current of 125 nA (typ) and is available in a small 1.5-

mm × 1.5-mm WSON package, making the device
