Overview
The DA9232-81VZ2 is a nano-power PMIC designed for low-power connected devices. It integrates a 300mA step-down DC/DC converter and a 100mA LDO/load switch within a compact 12-pin WLCSP package measuring 1.65mm x 1.25mm. The device features an I2C interface for configuration, dynamic voltage control (DVC), and ultra-low quiescent current of 750nA in shutdown mode. Input voltage ranges from 2.5V to 5.5V, with adjustable output voltages supporting efficient power management for battery-operated applications.
Feature Summary
- Ultra-low static current operation extending battery life
- Integrated dynamic voltage control for system optimization
- Configurable LDO function as load switch
- Compact WLCSP packaging for space-constrained designs
Applications
- Wearable devices such as smartwatches and ear-worn equipment
- Smart home devices including thermostats and door locks
- Portable medical equipment
- Smoke detectors and sensors
Procurement Notes
Verify the specific suffix '81VZ2' against official Renesas documentation to confirm exact tape-and-reel quantity and RoHS compliance status. Ensure compatibility with standard I2C addressing and check for any engineering model restrictions or availability limitations associated with this specific ordering code.
Selection Notes
Select this component for applications requiring minimal footprint and extended battery longevity. The integrated DVC feature supports optimized power modes. Verify that the 300mA buck channel and 100mA LDO meet the peak current demands of the target processor or sensor load.
Part Context
This part belongs to the DA923x series of nano-power PMICs from Renesas. These devices are engineered for IoT and wearable markets where size and efficiency are critical. The series typically combines a synchronous buck converter with an LDO to provide flexible power rails for modern low-voltage SoCs.
Replacement Considerations
Consult official cross-reference lists for direct replacements. Generic equivalents may not match the specific 750nA quiescent current or DVC capabilities.
