AAT4687: Over-Voltage Protection Switch

Applications

Description

The AAT4687 OVPSwitch™ is a member of the Skyworks

Application Specific Power MOSFET (ASPM™) product family. It is

a P-channel MOSFET power switch with precise over-voltage

protection control, designed to protect low-voltage systems

against high-voltage faults up to +28 V. If the input voltage

exceeds the programmed over-voltage threshold, the P-channel

MOSFET switch is turned off to prevent damage to the output load

circuits. The AAT4687 is available with an internally programmed

over-voltage trip point or as an adjustable version programmed by

two external resistors.

 Cell phones

 Digital still cameras

 GPS

 MP3 players

 Personal data assistants (PDAs)

 USB hot-swap/live-insertion devices

Features

The AAT4687 includes an under-voltage lockout (UVLO) protection

circuit, which puts the device into sleep mode at low input

voltages, consuming less than 1 A of current. The AAT4687 also

includes an enable pin (EN) to enable or disable the device and an

OVP, OTP fault indicator (FLT).

 Over-voltage protection up to 28 V

 Fixed or adjustable over-voltage protection threshold

 3 V under-voltage lockout threshold

 Fast OVP response:

The AAT4687 is offered in a small 10-pin, 2.2 mm  2.0 mm

SC70JW package, and is specified for operation over the 40 °C

to +85 °C ambient temperature range.

 0.7 s typical to over-voltage transient

 Low operation quiescent current:

 30 A typical

A typical application circuit is shown in Figure 1. The pin

configurations are shown in Figure 2. Signal pin assignments and

functional pin descriptions are provided in Table 1.

 1 A max in shutdown (disabled)

 Thermal shutdown protection

 100 m typical (130 m Max.) RDS(ON) at 5 V

 OVP, OTP fault indicator

VIO + 5 V

 1.8 A maximum continuous current
