Advanced Battery Management PMIC with Ultra Low Power Buck and Buck Boost Data Sheet ADP5360 FEATURES GENERAL DESCRIPTION Linear battery charger The ADP5360 combines one high performance linear charger High accuracy and programmable charge terminal voltage for a single lithium-ion (Li-Ion)/lithium-polymer (Li-Poly) and charge current up to 320 mA battery with a programmable, ultralow quiescent current fuel Compliant with JEITA charge temperature specification gauge and battery protection circuit, one ultralow quiescent Li-Ion and Li-Poly battery monitor and protection buck, one buck boost switching regulator, and a supervisory Voltage-based fuel gauge with adaptive filter limitation circuit that can monitor output voltage. Independent battery protection of overcharge and The ADP5360 charger operates at up to 6.8 V to prevent USB overdischarge bus spiking during disconnect or connect scenarios. Temperature sensor with external NTC Ultralow quiescent current buck converter The ADP5360 features an internal isolation field effect transistor Quick output discharge option (FET) between the linear charger output and the battery node. Ultralow quiescent current buck boost converter The full battery protection features are activated when the device is Quick output discharge option in the battery overcharge and overdischarge fault conditions. MR Supervisory with manual reset ( ) and watchdog timer The ADP5360 fuel gauge uses a voltage-based algorithm with Shipment mode extends battery life 2 an adaptive filter limitation solution. The fuel gauge reports Full I C programmability with dedicated interrupt pin real-time battery state of charge (SOC) for the rechargeable APPLICATIONS Li-Ion battery with ultralow quiescent current. Rechargeable Li-Ion/Li-Poly battery-powered devices The ADP5360 buck regulator operates at 1.0 MHz switching Portable consumer devices frequency in forced pulse-width modulation (FPWM) mode. Portable medical devices In hysteresis mode, the regulator achieves excellent efficiency at Wearable devices a low output power. The ADP5360 buck boost regulator only operates in hysteresis mode and outputs a voltage less than or greater than the battery voltage. The ADP5360 supervisory circuits monitor the regulator output voltage and provide a power-on reset signal to the system. A watchdog timer and an external pushbutton can reset the microprocessor. 2 The I C-compatible interface enables the programmability of all battery charging parameters, the protection threshold, the buck output voltage, and the status bit readback. The ADP5360 operates over the 40C to +85C junction temperature range and is available in a 32-ball, 2.56 mm 2.56 mm wafer level chip scale package (WLCSP).
