SNVSAP6B –SEPTEMBER 2017–REVISED JUNE 2020

LM5150-Q1 Wide VIN Automotive Low I_QBoost Controller

1 Features

2 Applications

•

AEC-Q100 qualified:

•

Automotive start-stop system

Automotive emergency call system

Battery-powered boost converters

–

Device temperature grade 1: –40°C to +125°C

ambient operating temperature range

–

Device HBM ESD classification level 2

Device CDM ESD classification level C4B

3 Description

The LM5150-Q1 device is a wide input range

automatic boost controller. The device is suitable for

use as a pre-boost converter which maintains the

output voltage from

vehicle battery during

automotive cranking or from a back-up battery during

the loss of vehicle battery.

Wide VIN input range from 1.5 V to 42 V when

VOUT ≥ 5 V (65-V absolute maximum)

•

Low shutdown current (I_Q≤ 5 µA)

Low standby current (I_Q≤ 15 µA)

The LM5150-Q1 switching frequency is programmed

by a resistor from 220 kHz to 2.3 MHz. Fast switching

(≥ 2.2 MHz) minimizes AM band interference and

allows for a small solution size and fast transient

response.

Four programmable output voltage options and

two selectable configurations

–

6.8 V, 7.5 V, 8.5 V, or 10.5 V

The LM5150-Q1 operates in low I_Qstandby mode

when the input or output voltage is above the preset

standby thresholds and automatically wakes up when

the output voltage drops below the preset wake-up

threshold.

Start-stop or E-call configurations

•

Adjustable switching frequency from 220 kHz to

2.3 MHz

•

Automatic wake-up and standby mode transition

Optional clock synchronization

Boost status indicator

The device transients in and out of the low I_Qstandby

mode to extend battery life at light load. A single

resistor programs the target output regulation voltage

as well as the configuration. Additional features

include low shutdown current, boost status indicator,

adjustable cycle-by-cycle current limit, and thermal

shutdown.

1.5-A peak MOSFET gate driver
