The LM51501-Q1 from Texas Instruments is a wide input range automatic boost controller designed for automotive applications. It can maintain a stable output voltage during vehicle cranking from a battery or backup battery.
This device supports a wide input voltage range from 1.5 V to 42 V, with an absolute maximum rating of 65 V. It offers four programmable output voltage options: 6.0 V, 6.5 V, 9.5 V, or 11.5 V, and can be configured for start-stop or e-call applications. The switching frequency is adjustable from 220 kHz to 2.3 MHz, allowing for minimized AM band interference and smaller solution sizes.
Key features include low shutdown current (≤ 5 µA) and low standby current (≤ 15 µA) to extend battery life. It also has a 1.5-A peak MOSFET gate driver, adjustable cycle-by-cycle current limit, and thermal shutdown protection. The LM51501-Q1 is AEC-Q100 qualified, temperature grade 1, with HBM ESD classification level 2 and CDM ESD classification level C4B.
Packaged in a 16-pin WQFN with dimensions of 4 mm x 4 mm, this controller is suitable for surface mount applications. It is designed to aid functional safety system design, with documentation available.
