STMicroelectronics has announced the latest generation of its pace-setting switch ICs 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, as per ST.
ST explains intelligent high-side switches provide a more reliable and efficient replacement for conventional relays. ST offers its VIPower family in common package style for many devices in the range allowing tier-one suppliers to build several module variants using the same basic hardware and software so car makers can address differing requirements in international markets and offer various model specifications and options cost-effectively. The common-package approach has become widely adopted among high-side switch vendors, says ST.
This new M0-7 series is the seventh generation of ST’s VIPower family with 75% of family members are available in a 5 x 4mm package, which is 40% smaller than the smallest competing devices, claims ST.
Advantages include space saving on the board, performance improvements such as greater protection against short circuits, more accurate voltage and temperature feedback, increased current-sense precision, and best-in-class electromagnetic emission (EMI) performance.
Samples of all family members are available now. The first device to enter production will be the dual-channel VND7020AJ-E, in Q2 2013, priced from $1.10 for orders over 1,000 pieces. The full range of package types available across the new family will include PowerSSO-16, PowerSSO-36, Octapak, and SO-8.
Major features of M0-7 series:
• 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
