DA9072-80V32

Power Management - Specialized Overview

The DA9072-80V32 is a configurable Power Management IC (PMIC) designed for wearable applications. It features an ultra-low quiescent current buck converter with 800 nA no-load battery current, programmable down to 0.6 V and capable of 300 mA output. The device includes linear chargers, ultra-low Iq LDOs, and a 12 V boost converter. It operates within an input voltage range of 1.4 V to 3.3 V and supports output voltages from 4.5 V to 18 V. The component is housed in a WLCSP-42 package and functions between -40°C and +85°C.

Power Management - Specialized Procurement Notes

Verify the specific suffix '80V32' against official Renesas documentation to confirm pinout and functional configuration. Ensure compatibility with the required WLCSP-42 footprint and thermal constraints. Cross-reference the operating temperature range (-40°C to +85°C) with system environmental specifications. Confirm that the 300 mA buck converter capability meets peak load requirements without exceeding thermal limits.

Power Management - Specialized Selection Notes

Select this PMIC for applications requiring minimal standby power consumption due to its 800 nA buck converter quiescent current. The integrated linear charger and analog battery monitors simplify design by reducing external component count. Verify that the 1.4 V to 3.3 V input range aligns with the primary power source. Consider the WLCSP-42 package size constraints for compact wearable form factors.

Power Management - Specialized Part Context

The DA9072 belongs to the Renesas DA9070 series of specialized PMICs. This family targets wearable electronics with high integration levels. The DA9072 variant specifically emphasizes ultra-low quiescent current performance compared to other family members. It shares architectural similarities with the DA9070 but offers distinct current and voltage configurations optimized for specific battery management tasks.

Power Management - Specialized Replacement Considerations

Consult official Renesas substitution lists for verified alternatives. Generic PMIC replacements may not match the specific 800 nA quiescent current or WLCSP-42 package dimensions. Ensure any substitute supports the same I2C configurability and analog battery monitor interface.
