Low-power solution for MEMS switches and high-voltage drivers
19 January 2023
Menlo Micro recently announced the qualification and production release of the MM101, an 8-channel, low-voltage to high-voltage driver with 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 highly 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.
