Leading global semiconductors specialist, ST Microelectronics has introduced an advanced range of intelligent high-side switches for smaller, smarter automotive electronics.

Setting new standards in miniaturisation and precision, and leveraging package commonality for flexibility and scalability, ST’s latest generation of pace-setting switch ICs, the M0-7 series is ideal for vehicle electronics such as lights and body modules. The new devices provide enhanced intelligent features, improve protection and reliability, and are up to 40% smaller than competing alternatives.

ST’s M0-7 series intelligent high-side switches provide a more reliable and efficient replacement for conventional relays. For several generations, ST’s VIPower family has offered advantages such as a common package style for many devices in the range, enabling tier-one suppliers to build several module variants using the same basic hardware and software so that car makers can address differing requirements in international markets and offer various model specifications and options cost-effectively.

The M0-7 series, the 7th generation of ST’s VIPower family has 75% of family members available in a 5 x 4mm package, which is 40% smaller than the smallest competing devices. This package size allows car electronics designers to save PC-board space and aim for smaller module sizes.

Various internal design changes in these high-side switches increase precision, enhance diagnostic feedback, and improve reliability. Performance improvements in the M0-7 series include greater protection against short circuits, more accurate voltage and temperature feedback, increased current-sense precision, and best-in-class EMI performance.

Key features of M0-7 series automotive high-side switches:

  • Precise load-current, voltage and temperature-monitor feedback
  • Integrated sense multiplexer
  • Power-limitation and over-temperature latch-off
  • Bulb/ LED mode (quad channel)
  • Flexible fault-reset management
  • Reverse-polarity protection
  • Full on- and off-state diagnostics capability
  • Ultra-low quiescent current
