MM101-02ADA-TR

Overview

The MM101-02ADA-TR is an 8-channel high-voltage driver IC from Menlo Microsystems, designed as a low-voltage serial-to-high-voltage parallel converter. It features push-pull outputs and an internal charge pump converter. The device operates with a switching frequency of 33 MHz and supports a maximum operating temperature of +125°C. It is available in a QFN-32 package (5x5 mm) for surface mount applications.

Feature Summary

• Integrates an internal charge pump converter to generate high voltage from low-voltage inputs
• Provides eight independent channels with push-pull output drivers
• Converts low-voltage serial signals to high-voltage parallel outputs

Applications

• MEMS microphone biasing and driving
• High-voltage generation for integrated sensor arrays
• Driver circuits for micro-electromechanical systems requiring compact form factors

Procurement Notes

Verify the specific suffix 'ADA' confirms the QFN-32 package variant when ordering. Confirm RoHS compliance status with the supplier prior to procurement. Ensure the required quantity matches the tape and reel packaging specifications provided by the manufacturer. Check for any moisture sensitivity level requirements during storage and handling.

Selection Notes

Select this component when an 8-channel high-voltage driver is required within a small footprint. The internal charge pump eliminates the need for external inductors or capacitors typically associated with voltage conversion. Consider the 33 MHz switching frequency and thermal limits when designing the power management system.

Part Context

This part belongs to the MM101 series of switch-mode regulators and high-voltage drivers. The series is specifically engineered for MEMS applications where space constraints and integration levels are critical. It serves as a dedicated interface between low-voltage digital control logic and high-voltage MEMS actuators or sensors.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pin compatibility and electrical specifications if considering alternative high-voltage driver ICs from other manufacturers.
