The A89503KLPTR-5 is an 80V automotive half-bridge MOSFET driver designed for high-power inductive loads in automotive applications. It operates within a supply voltage range of 5.5 to 80 V and features a bootstrap gate drive for N-channel MOSFETs, allowing independent control of high-side and low-side gate drives. The device includes a charge pump regulator for low supply voltage operation and supports control via direct logic inputs or an SPI-compatible serial interface. Integrated diagnostics provide fault indication and protection for the power MOSFETs under various conditions. The A89503KLPTR-5 is AEC-Q100 Grade 0 qualified, making it suitable for safety-critical systems, and is packaged in a 24-lead TSSOP with an exposed pad for improved thermal performance.
The A89503 offers robust and reliable gate drive for N-channel MOSFETs in automotive applications. It supports a wide voltage range (5.5V to 80V), offers programmable gate drive and current sensing, and includes comprehensive diagnostics for enhanced system monitoring and protection.
