Intelligent high-side switch has automotive system reliability

Diodes has introduced its first protected, automotive-compliant, high-side IntelliFET, the ZXMS81045SPQ. It can deliver high power from a small footprint, while also providing protection and diagnostic capabilities. It is suitable for driving 12V automotive loads, such as LEDs, bulbs, actuators, and motors in automotive body control and lighting systems.

The ZXMS81045SPQ features a 41V-rated N-channel FET with on-board circuitry that protects against short circuits, manages inrush currents, and safeguards against over-voltage conditions including load dumps. 

The ZXMS81045SPQ also features over-temperature protection with auto-restart, and protection against electrostatic discharges (ESD). Loss of ground and reverse polarity protection can also be implemented with the aid of a few external components.

A dedicated current sense (IS) pin provides precision analogue current monitoring of the output and fault indication for short to battery, short to ground and open load detection. 

The ZXMS81045SPQ provides an efficient, reliable, smaller footprint alternative to relays, fuses, and discrete circuits. It is also a form, fit and functional equivalent for existing power switch devices, advises Diodes.

The ZXMS81045SPQ is qualified to AEC-Q100, is PPAP capable and manufactured in IATF 16949 certified facilities. It is supplied in a SO-8EP package.

Diodes provides semiconductor products to companies in the consumer electronics, computing, communications, industrial, and automotive markets. It has an expanded product portfolio of discrete, analogue and mixed-signal products and packaging technology to meet customers’ needs. 

It has a range of application-specific solutions and sales, with worldwide operations of 32 sites, including engineering, testing, manufacturing, and customer service for high volume, high growth markets.
