Overview
The BOS1901CQR is a piezo haptic driver with a digital front end in a QFN package. It operates on a supply voltage of 3 V to 5.5 V with a current consumption of 14.5 mA. The device supports an operating temperature range from -40 °C to +85 °C and utilizes SMD/SMT installation. It features a WLCSP-20 or QFN-24 package configuration depending on the specific suffix variant, though the CQR designation typically aligns with the QFN-24 form factor within the BOS1921 series context provided in comparative data. The driver generates high-voltage outputs up to 190 Vpp for actuator control.
Feature Summary
- Integrates a digital front end for precise waveform generation
- CapDrive technology enables efficient piezo actuator driving
- Supports standard digital interfaces for system integration
Applications
- Piezo haptic feedback systems
- Mobile device vibration modules
- Wearable technology actuators
Procurement Notes
Verify the exact package type (QFN vs WLCSP) against the manufacturer's official datasheet for the BOS1901CQR, as naming conventions may overlap with the BOS1921 series. Confirm RoHS compliance status and moisture sensitivity level prior to PCB assembly planning. Ensure the selected variant matches the required thermal performance for the intended application environment.
Selection Notes
Select this component when a compact solution for piezo haptic drivers is required with low power consumption. Compare the BOS1901CQR against the BOS1921 series for package size differences. Consider the operating voltage range and output capabilities relative to the connected piezo actuator specifications. Evaluate the digital interface compatibility with the host microcontroller.
Part Context
The BOS1901CQR belongs to Boreas Technologies' portfolio of piezo haptic drivers. It is part of a family that includes variants like the BOS1901CWR and BOS1921 series. These components are designed to provide high-performance haptic feedback in space-constrained electronic devices. The series emphasizes low power usage and high voltage output generation for effective tactile sensation.
Replacement Considerations
The BOS1901CWR is a related variant in the same product line but differs in package type (WLCSP). The BOS1921CQR offers similar functionality in a QFN package. Verify pinout compatibility and electrical parameters before substituting.
