110VPK-PK High-Efficiency Piezo Haptic Actuator Boost Driver

Lowest Power Piezo Haptic Actuator Driver


点击查看特定型号的库存状况。

说明

The MAX77501 is a high-efficiency controller driver for piezo haptic actuators and is optimized for driving up to 2µF piezo elements. It can generate a single-ended haptic waveform of up to 110VPK-PK amplitude from a 2.8V to 5.5V input power supply or a single cell Li+ battery. Memory playback and haptic waveforms real-time streaming modes are supported.

A 25MHz SPI interface provides full system access and control, including fault reporting and monitoring. This allows for a rapid 600µs playback start-up time from shutdown. The on-board memory can be dynamically allocated as multiple waveforms storage or as a FIFO buffer. The IC also implements an ultra-low power boost architecture providing the lowest power consumption solution for a haptic actuator driver.

Built-in undervoltage lockout (UVLO), cycle-by-cycle overcurrent limit, overvoltage and thermal shutdown protections ensure safe operation under abnormal operating conditions.

The MAX77501 is available in a 30-bump, 0.4mm pitch, wafer-level package (WLP).
