DRV2911-Q1 integrates two H-bridges for driving piezo-based Lens Cover Systems, LCS, up to 40V absolute maximum capability while maintaining a very low RDS(ON) to reduce switching losses. DRV2911-Q1 integrates a power management LDO (3.3V / 30mA) and buck converter (5.0V to 5.7V, ≤200mA) that can be used to power external circuits like the Ultrasonic Lens Cleaning (ULC) controller, ULC1001.
Each output driver channel consists of N-channel power MOSFETs configured in a half-bridge configuration. Two independent PWM inputs drive each half-bridge. The DRV2911-Q1 includes a 30mA, 3.3V LDO regulator.
Several protection features including supply undervoltage lockout (UVLO), charge pump undervoltage (CPUV), overcurrent protection (OCP), over-temperature warning (OTW), and over-temperature shutdown (OTSD) are integrated into DRV2911-Q1 to protect the device and system against fault events. Fault conditions are indicated by the FAULTZ pin. The fault pin can also be tied to the controller device, like ULC1001-Q1, where a fault can be recognized over I2C.
