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 I_Q 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 I_Q 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.
