TPS3899

SLVSFM0B – SEPTEMBER 2020 – REVISED JANUARY 2022

TPS3899 Nano-Power, Precision Voltage Supervisor, Push-Button Monitor with

Programmable Sense and Reset Delay

1 Features

3 Description

•

Functional Safety-Capable

– Documentation available to aid functional safety

system design

The TPS3899 is a nano power, precision voltage

supervisor with ±0.5% threshold accuracy and

programmable sense and reset time delay in a 6-pin

space saving 1.5 mm x 1.5 mm WSON package.

The TPS3899 is a feature-rich voltage supervisor that

offers the smallest total solution size in its class. Built-

in hysteresis along with programmable delay prevent

false reset signals when monitoring a voltage rail or

push button signals.

•

Precision voltage and push-button monitor

VDD range: 0.85 V to 6 V ( DL and PL outputs)

VDD range: 1 V to 6 V ( PH output)

Programmable sense and reset delay

Nano quiescent current: 125 nA (typ)

High threshold accuracy: ±0.5% (typ)

Precision hysteresis: 5% (typ)

Adjustable threshold voltage: 0.505 V (typ)

Fixed threshold voltage: 0.8 V to 5.4 V

– Fixed threshold level available in 100 mV steps

Multiple output topologies

– DL: open-drain active-low

– PL: push-pull active-low

– PH: push-pull active-high

Temperature range: –40°C to +125°C

Package: 1.5-mm × 1.5-mm WSON

The separate VDD and SENSE pins allow for

the redundancy sought by high-reliability systems.

SENSE is decoupled from VDD and can monitor rail

voltages other than VDD. Optional use of external

resistors are supported by the high impedance input

of the SENSE pin. Both CTS and CTR provide delay

adjustability on the rising and falling edges of the

RESET signals. CTS also functions as a debouncer

by ignoring voltage glitches on the monitored voltage

rails and operates as a "manual reset" that can be

used to force a system reset.

•

2 Applications

The precision performance, best in-class features

in a compact form factor, makes the TPS3899

an ideal solution for wide ranging industrial and

battery-powered applications such as Factory/Building

Automation, Motor Drives, and consumer products.

The device is fully specified over a temperature range

of –40°C to +125°C (T_A).
