1 / 87 page  PCA9420 Power management IC for low-power microcontroller applications Rev. 4.0 — 28 November 2022 Product data sheet 1 General description The PCA9420 is a highly integrated Power Management IC (PMIC), targeted to provide a full power management solution for low-power microcontroller applications or other similar applications. The device consists of a linear battery charger capable of charging up to 315 mA current. It has an I2C programmable Constant Current (CC) and Constant Voltage (CV) values for flexible configuration. Various built-in protection features such as input overvoltage protection, overcurrent protection, thermal protection, etc. are also provided for safe battery charging. It also features JEITA-compliant charging. The device also integrates two step-down (buck) DC-DC converters which have I2C programmable output voltage. Both buck regulators have integrated high-side and low- side switches and related control circuitry, to minimize the external component counts; a Pulse-Frequency Modulation (PFM) approach is utilized to achieve better efficiency under light load condition. Other protection features such as overcurrent protection, under-voltage lockout (UVLO), etc., are also provided. By default, the input for these regulators is powered by either VIN or VBAT, whichever is greater. In addition, two on-chip LDO regulators are provided to power up various voltage rails in the system. Other features such as Fm+ I2C-bus interface, chip enable, interrupt signal, etc. are also provided. The chip is offered in 2.09 mm x 2.09 mm, 5 x 5 bump, 0.4 mm pitch WLCSP package; and 3 mm x 3 mm, 24-pin QFN package. 2 Features and benefits • Linear battery charger for charging single cell li-ion battery – 20 V tolerance on VIN pin – Programmable input OVP (5.5 V or 6 V) – Programmable constant current (up to 315 mA) and pre-charge low voltage current threshold – Programmable constant voltage regulation – Programmable automatic recharge voltage and termination current threshold – Built-in protection features such as input OVP, battery SCP, thermal protection – JEITA compliant – Battery attached detection – Over-temperature protection • Two step-down DC-DC converters – Very low quiescent current – Programmable output voltage |
