- The MM101 is a highly integrated driver that is easy to program and control.
- The MM101 high–voltage driver can be configured in a daisy-chain mode.
MM101 from Menlo Micro is an 8-channel, low-voltage to the 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. It has multiple safety features including power-on-reset, power ON/OFF sequence control, and under-voltage protection for the charge pump and supply voltage.The MM101 driver provides a compact, power-efficient solution for driving the MEMS-based switches, thus bringing size, weight, power and cost benefits to MEMS control applications.
The highly integrated voltage divider 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’s SPI can be configured in a daisy chain method because the high-voltage driver features selectable communication interfaces (SPI, GPIO) with up to 33 MHz SPI clocking speed.
The driver’s communication interface supports interface fault indicators, power-on-reset, power ON/OFF sequence control, and under-voltage protection for the charge pump and supply voltage. According to the company, the MM101’s highly integrated driver design reduces board layout space and BOM costs compared to the industry’s common multi-chip, high-voltage driver solutions for controlling MEMS devices.
“The new MM101 driver provides a miniature, low-power solution for driving our MEMS-based switches and other Ideal Switch products, bringing size, weight, power and cost benefits to a wide range of applications,” said Chris Giovanniello, co-founder and SVP marketing, Menlo Micro. “We developed this high-voltage driver solution to simplify the creation of highly integrated, multi-chip modules that are easy to program and control. Using the MM101 in system designs, customers will be able to reduce the board space required for driving multiple switches, as well as have the option to integrate our new driver into their own custom modules.”
