The new VIPower™ M0-7 H-bridge family is a set of fully integrated and protected bridge circuits especially designed for DC motor control. Covering a wide range of load conditions, thanks to scalable power stages and packages, its combination of state-of-the-art embedded DC or 20-kHz PWM speed control modes with an embedded protection mechanism makes it the ideal solution for driving DC motors in cars. Further embedded features including independent load current sensing on each branch of the H-bridge and open load in off-state as well as chip temperature and VCC reading enhance system simplicity and flexibility, avoiding having to use external components.
Key benefits of VIPower™ M0-7 H-bridges
Targeting different DC motors
The availability of different on-state resistance (RON) classes in the same package ensures flexible driving and control of various DC motors from a few watts up to 200 W in automobiles:
- Full H-bridge configuration
- Double-half H-bridge configuration
- Cascaded configuration
New MultiSense diagnostics
Output current is multiplexed through selectors and reports:
- In ON state: current on each leg, chip temperature, VCC reading, and short circuit/overload flags
- In OFF state: open load, output shorted to battery or GND
Advanced tiny power packages
Body size reduced up to 70% versus previous family for PCB shrinkage and system weight reduction.
- PowerSSO-36 (single- and triple-pad)
Ultra-low power consumption
Maximum 3 µA standby current for low- and high-power DC motors. This keeps the power consumption of the module low in spite of the increased electronic components on board.
