30591 Engine Control Unit Power Driver IC – Automotive ECU Power Supply Chip, High Efficiency, Overcurrent Protection

The 30591 is a specialized power management and gate driver IC designed for automotive engine control modules (ECU) and engine computer board power supply systems.
It integrates multiple low-side and high-side drivers capable of controlling relays, solenoids, and injectors directly.
The device operates efficiently under a wide input voltage range suitable for 12V and 24V vehicle electrical environments.
Built-in overcurrent protection, overtemperature shutdown, and short-circuit handling ensure robust performance in harsh under-hood conditions.
This chip reduces external component count, simplifying printed circuit board (PCB) design for engine control units.
It features low quiescent current during standby, helping meet automotive power consumption standards.
Typical applications include engine management systems, transmission control units, and aftermarket automotive computer repairs.
The 30591 enhances system reliability by providing diagnostic feedback for open load and overvoltage conditions.
