DUAL CHANNEL PRECISION ADJUSTABLE CURRENT-LIMITED POWER SWITCH

Check for Samples: TPS2561-Q1

FEATURES

DESCRIPTION

The TPS2561-Q1 is a dual-channel power-distribution

switch intended for applications where precision

current limiting is required or heavy capacitive loads

and short circuits are encountered. These devices

offer a programmable current-limit threshold between

250 mA and 2.8 A (typ) per channel through an

external resistor. The power-switch rise and fall times

are controlled to minimize current surges during turn

on or off.

•

Qualified for Automotive Applications

Two Separate Current Limiting Channels

Meets USB Current-Limiting Requirements

Adjustable Current Limit, 250 mA–2.8 A (typ)

± 7.5% Current-Limit Accuracy at 2.8 A

Fast Overcurrent Response - 3.5-μS (typ)

Two 44-mΩ High-Side MOSFETs

Operating Range: 2.5 V to 6.5 V

•

Each channel of the TPS2561-Q1 device limits the

output current to a safe level by switching into a

constant-current mode when the output load exceeds

the current-limit threshold. The FAULTx logic output

for each channel independently asserts low during

overcurrent and over temperature conditions.

2-μA Maximum Standby Supply Current

Built-in Soft-Start

15 kV or 8 kV System-Level ESD Capable

UL Listed – File No. E169910
