High-side drivers meet LV124 cold-cranking specification

The VND7050AJ12 and VND7140AJ12 have a minimum supply voltage of 3.2V to keep essential equipment such as dashboard instruments operating as the vehicle battery voltage dips during engine cranking. The ST devices provide a compact and reliable replacement for electromechanical relays and associated circuitry, and are 40% smaller than the nearest competing high-side drivers.

As the latest members of ST’s VIPower M0-7 family, the drivers have built-in multiplexed current-sense diagnostics that provide precise analogue load-current feedback. The best-in-class EMI performance exceeds CISPR 25 specifications. Together these features minimise demand for external sensing and filtering components.

Further advantages common to ST’s VIPower M0-7 devices include ultra-low quiescent current, which minimises drain on the battery in idle mode, configurable auto-restart protection against hazardous conditions and Grade-A short-circuit robustness up to one million cycles. The wide range of VIPower M0-7 drivers offers extensive package and pin compatibility, as well as low cost per channel, to simplify design standardisation, scalability and management of module variants.
