LM5060

High-Side Protection Controller with Low Quiescent

Current

General Description

Features

The LM5060 high-side protection controller provides intelli-

gent control of a high-side N-Channel MOSFET during normal

on/off transitions and fault conditions. In-rush current is con-

trolled by the nearly constant rise time of the output voltage.

A power good output indicates when the output voltage reach-

es the input voltage and the MOSFET is fully on. Input Under-

Voltage Lock-Out, with hysteresis, is provided as well as

programmable input Over-Voltage Protection. An enable in-

put provides remote On / Off control. The programmable

Under-Voltage Lock-Out input can be used as second enable

input for safety redundancy. A single capacitor programs the

initial start-up V_GSfault detection delay time, the transition

V_DSfault detection delay time, and the continuous Over-Cur-

rent V_DSfault detection delay time. When a detected fault

condition persists longer than the allowed fault delay time, the

MOSFET is latched off until either the Enable input or the Un-

der-Voltage Lock-Out input is toggled low and then high.

Available in Automotive grade / AEC Q-100

■

Wide operating input voltage range: +5.5V to +65V

Less than 15 µA quiescent current in disabled mode

Controlled output rise time for safe connection of

capacitive loads

Charge pump gate driver for external N-Channel MOSFET

■

Adjustable Under-Voltage Lock-Out (UVLO) with

hysteresis

UVLO serves as second enable input for systems

requiring safety redundancy

■

Programmable fault detection delay time

■

MOSFET latched off after load fault is detected

Active low open drain POWER GOOD (nPGD) output

Adjustable input Over-Voltage Protection (OVP)

Immediate restart after Over-Voltage shutdown
