Description

The FAN8831 is a single-chip piezoelectric actuator

driver consisting of step-up DC-DC converter with

integrated 36 V boost switch and a full-bridge output

stage. The device is capable of driving a Piezo bi-

directionally at 120 V peak-to-peak from a single 3 V

lithium cell. The step-up DC-DC converter operates in

Critical Conduction Mode (CRM) and is optimized to

work in a coupled inductor configuration to provide

output voltages

in excess of 60 V. Over-voltage

protection,

over-current

protection

and

thermal

shutdown are all provided. An internal ready is used to

enable the full-bridge gate driver when step-up DC-DC

converter output voltage reaches the proper level with

hysteresis.

The boost voltage is set using external resistors, and

step-up current limit is programmable via the external

resistor at OCP pin.

The output H-bridge features four integrated 75 V P and

N-channel for sine wave drive of the Piezo actuator.
