Advanced Battery Management PMIC with
Ultra Low Power Buck and Buck Boost
ADP5360
Data Sheet
FEATURES
GENERAL DESCRIPTION
Linear battery charger
High accuracy and programmable charge terminal voltage
and charge current up to 320 mA
Compliant with JEITA charge temperature specification
Li-Ion and Li-Poly battery monitor and protection
Voltage-based fuel gauge with adaptive filter limitation
Independent battery protection of overcharge and
overdischarge
The ADP5360 combines one high performance linear charger
for a single lithium-ion (Li-Ion)/lithium-polymer (Li-Poly)
battery with a programmable, ultralow quiescent current fuel
gauge and battery protection circuit, one ultralow quiescent
buck, one buck boost switching regulator, and a supervisory
circuit that can monitor output voltage.
The ADP5360 charger operates at up to 6.8 V to prevent USB
bus spiking during disconnect or connect scenarios.
Temperature sensor with external NTC
Ultralow quiescent current buck converter
Quick output discharge option
Ultralow quiescent current buck boost converter
Quick output discharge option
The ADP5360 features an internal isolation field effect transistor
(FET) between the linear charger output and the battery node.
The full battery protection features are activated when the device is
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
an adaptive filter limitation solution. The fuel gauge reports
real-time battery state of charge (SOC) for the rechargeable
Li-Ion battery with ultralow quiescent current.
Shipment mode extends battery life
Full I2C programmability with dedicated interrupt pin
APPLICATIONS
Rechargeable Li-Ion/Li-Poly battery-powered devices
Portable consumer devices
Portable medical devices
Wearable devices
The ADP5360 buck regulator operates at 1.0 MHz switching
frequency in forced pulse-width modulation (FPWM) mode.
In hysteresis mode, the regulator achieves excellent efficiency at
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.
The I2C-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 −40°C to +85°C junction
temperature range and is available in a 32-ball, 2.56 mm ×
2.56 mm wafer level chip scale package (WLCSP).
