Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Shenzhen Mingjiada Electronics Co., Ltd. supplies and acquires Motor Control LV8968BBUWR2G Multi-purpose 3-phase brushless DC pre-driver for automotive applications, developed to meet ISO 26262 standards.

LV8968BBUWR2G Device Description

This three-phase peripheral pre-driver provides a BEMF (reverse electromotive force) output, and its wide operating voltage range and AEC-Q100 certification make it ideal for automotive applications. Six gate drivers provide 400 mA (typical) of gate current to the external power bridge, allowing the use of low-resistance power FETs and logic level FETs, all of which are protected against over-current, short-circuit, over-temperature, and gate under-voltage. Multiple protection and monitoring features make this device suitable for applications with functional safety (FuSa) requirements. Three independent low-side source pins allow multiple shunt measurements to accommodate external FOC (Field Oriented Control) options.

The device also includes a programmable linear regulator, a fast current-sense amplifier, and a windowed watchdog for microcontroller and FOC support.
