The LP28021AQVF PMIC - Battery Management TDFN-10 RoHS is an integrated battery management device manufactured by LOWPOWER. This electronic part is designed with a low voltage distribution and integrates multiple protection features to monitor and protect a Li-ion battery during charge, discharge, and power-on/off conditions in small form factor applications. It provides system power supply, charging control, and protection management functions. The LP28021AQVF includes an integrated variable frequency switching buck converter, adjustable charging current limiting circuitry, low quiescent current sleep mode and high NTC thermistor static current for monitoring the temperature of the Li-ion battery. The LP28021AQVF is housed in a 10-pin Thin shrink Dual Flat No-leads (TDFN) package with RoHS compliant, making it a highly suitable low-cost and reliable solution for a wide variety of applications, including wearables, wireless earbuds, and other devices.
