TPS3704

SNVSBZ2B – MARCH 2021 – REVISED DECEMBER 2021

TPS3704x Quad, Triple, Dual, Single Window or Standard Voltage Supervisor

1 Features

3 Description

•

Designed for high performance and safety:

– Input current (4 channels): I_DD= 15 μA

(maximum)

– High threshold accuracy: ±1% (maximum)

– Built-in precision hysteresis:

V_HYS(V_IT> 800 mV) = 0.75% (typical)

Designed for a wide range of applications:

– Quad, triple, dual, or single voltage supervisor

The TPS3704x is a low-power precision window or

standard voltage supervisor that can be configured as

a quad, triple, dual, or single channel. Each channel

has a threshold accuracy of ±1% in an 8-pin

(1.6 mm x 2.9 mm) SOT-23 package offering a small

solution size. The TPS3704x includes a very accurate

threshold detection, with high resolution, that is ideal

for systems that operate on low-voltage supply rails

and have narrow margin supply tolerances. Built-in

low threshold hysteresis and a fixed reset delay (t_D

options from 20 μs to 1200 ms) prevent false reset

signals when monitoring multiple voltage rails.

•

TPS37044, 3, 2, 1: 4, 3, 2, 1 - channels

– Input voltage range, V_DD= 1.7 V to 6 V

– (UV / OV) threshold accuracy: ±0.1% (typical)

•

Each channel can be configured

independently: window, UV, or OV

Window tolerance: ±3% to ±11%

(can be programmed asymmetrical)

High threshold resolution:

The TPS3704x does not require any external

resistors for setting the over and under voltage

reset thresholds, which further optimizes overall high

accuracy, cost, solution size, and improves reliability

for safety systems.

V_IT≤ 0.8 V: 20 mV steps

V_IT> 0.8 V: lower of 0.5% or 20 mV steps

V_ITthreshold voltages for each individual

channel can be set independently

Separate VDD and SENSEx pins allow monitoring of

rail voltages other than VDD or can be used as a

push-button input. Optional use of external resistors

are supported by the SENSEx pins. Each channel on

the TPS3704x can be customized to its own over and

under voltage window detection with an upper and

lower threshold tolerance that can be symmetric or

asymmetric.

•

– Push-button monitor on all channels

– Reset time delay (t_D): fixed time delay options

Options: 23-fixed time options ranging from

20 µs (minimum) to 1200 ms (maximum)

– Temperature range: –40°C to +125°C

Multiple output topologies:

– TPS3704xxxO: open-drain, active-low (RESET)

– TPS3704xxxL: push-pull, active-low (RESET)

– TPS3704xxxH: push-pull, active-high (RESET)
