ADP5320

Wearable Power Management Solution for Multiple Battery Types

FEATURES

GENERAL DESCRIPTION

► Wide input supply voltage range: 1.8 V to 5.5 V

► Low quiescent current: 5.1 µA standby mode, including UVLO

► 16-bit coulomb counter fuel gauge with integrated high-side

current sensing resistor

► 12-bit ADC to monitor battery voltage, output voltages, and

junction temperature

The ADP5320 highly integrated power management unit (PMU)

combines nine digitally adjustable regulators, a fuel gauge, a 12-bit

analog-to-digital converter (ADC), 2 kb of one time programmable

(OTP) memory, anticounterfeit logic in a 42-ball, 2.880 mm ×

2.980 mm WLCSP. The regulators include: 2× buck-boost, 1× buck

regulator, 5× low dropout (LDO) regulators, and one low input LDO.

The ADP5320 meets demanding performance and board space

requirements for wearable applications.

► Channels 1 and Channel 2: 150 mA low power buck-boost

regulator

The ADP5320 operates from a 1.8 V to 5.5 V input supply voltage

range, enabling the device for use with multiple types of battery

inputs including: 2S/3S Zinc-air coin-cells or Li-poly/Li-ion batteries,

as well as other types of dc power sources.

► Selective buck, boost, or buck-boost operation

► Selective hysteresis or pulse-width modulation (PWM) mode

► Selective PWM frequency: 50 kHz to 225 kHz

► 2× programmable GPIOs for clock synchronization or fast stop

switching input

► Channel 3: 150 mA low power buck regulator

► Channel 4 Through Channel 6, and Channel 8: 50 mA low noise

LDO, 1.65 V to 5.5 V input supply voltage range

The ADP5320 PMU fuel gauge includes a precision 16-bit coulomb

counter that integrates battery current flowing through the device.

A 12-bit ADC is included to monitor battery voltage, output supply

voltages, and the junction temperature. Other features include a

programmable sequencing engine and system fault recovery.

► Channel 7: 50 mA sink current LDO

The ADP5320 PMU buck-boost regulators are high efficiency, step

up and step down regulators that operate at input voltages greater

than, less than, or equal to the regulated output voltage. All regula-

tors, including the six LDOs, are digitally programmable to meet

different power requirements for many applications.

► Channel 9: 50 mA, low noise LDO, 1.0 V to 1.9 V input supply

voltage range

► I²C interface with interrupt warning

► 2 kb OTP memory

► Power-good monitor and watchdog power hard reset

► UVLO, peak current-limit protection, and TSD protection

► Integrated anticounterfeit logic module

► 42-ball, 0.40 mm pitch, 2.880 mm × 2.980 mm WLCSP

► −10°C to +70°C operating junction temperature range

The ADP5320 includes a 2-wire, I²C-compatible, digital interface

and is rated at the −10°C to +70°C operating junction temperature

range.

APPLICATIONS

► Wearable medical applications

► Internet of Things (IoT) applications

► Disposable sensor devices

► Battery-powered devices
