BOS1931CWR

Overview

The BOS1931CWR is a high-efficiency single-chip piezo actuator driver manufactured by Boreas Technologies. It utilizes patented CapDrive technology to provide energy recovery for driving piezoelectric actuators with waveforms up to specified limits. The component operates within a supply voltage range of 3 V to 5.5 V and features an ultra-low quiescent current of 710 uA. Designed for surface-mount applications, it is housed in a WLCSP-25 package. The device integrates fully integrated control and power stages, supporting operation temperatures from -40°C to +85°C.

Feature Summary

• Integrates patented CapDrive technology for efficient energy recovery in piezo actuation
• Combines fully integrated control logic and power stage into a single chip
• Features ultra-low power consumption suitable for battery-operated devices

Applications

• Piezoelectric haptic feedback systems
• Micro-pump actuation
• Valve control mechanisms

Procurement Notes

Verify the specific suffix CWR corresponds to the WLCSP-25 packaging and reel configuration required for your assembly process. Confirm that the active status aligns with long-term availability needs. Ensure design-in documentation references the official datasheet for thermal and electrical characteristics. Cross-reference the manufacturer part number BOS1931CWR with distributor catalogs to confirm current production status and compliance certifications such as RoHS.

Selection Notes

Select this component when high efficiency and low power are critical for piezo actuator drivers. The integrated nature reduces external component count compared to discrete solutions. Consider the WLCSP-25 package constraints for PCB layout and soldering processes. Compare against the BOS1921 series if different interface requirements or pinout configurations are necessary for the target application.
