8-channel LV-HV driver integrates charge pump


Menlo Micro  is shipping an 8-channel, low-voltage to high-voltage driver with an integrated charge pump.

The MM101 driver provides a cost-effective solution for microelectromechanical system (MEMS) devices and other high-voltage driving applications in a highly integrated form factor.

Built as a companion to Menlo Micro’s Ideal Switch products, the MM101 provides up to eight drive outputs, programmable from 80 V or 90 V, in a miniature 5 mm x 5 mm 32-pin QFN or WLCSP flip-chip package powered with 5 V charge pump and 3.3 V driver circuit supply sources.


The MM101 high-voltage driver features selectable communication interfaces (SPI, GPIO) with up to 33 MHz SPI clocking speed, enabling SPI to be configured in a daisy-chain mode.

In addition, the driver’s communication interface supports interface fault indicators, power-on-reset, power ON/OFF sequence control, and under-voltage protection for charge pump and supply voltage.

The MM101’s integrated driver design reduces board layout space and BOM costs when compared to the industry’s common multi-chip, high-voltage driver solutions for controlling MEMS devices.

Features:

  • Eight high-voltage push-pull output channels
  • Internal charge pump voltage converter
  • Selectable communication interfaces (SPI, GPIO)
  • Available in a 5 mm x 5 mm QFN package and WLCSP flip-chip package

The MM101 is available today. Learn more at menlomicro.com.
