3 Description

The LM51501-Q1 is a wide input range automatic

boost controller. The device can be used to maintain a

stable output voltage during automotive cranking from

a vehicle battery or from a backup battery.

The LM51501-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.

The LM51501-Q1 operates in low IQ standby 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.

The device transitions in and out of low IQ standby

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. A status indicator can be used to control

a circuit to bypass the diode when the part is not

boosting in order to reduce power dissipation. In

E-call mode, the device can be used to control a

disconnect switch to protect the backup-battery.
