Data Sheet ADP5320 Wearable Power Management Solution for Multiple Battery Types FEATURES GENERAL DESCRIPTION Wide input supply voltage range: 1.8 V to 5.5 V The ADP5320 highly integrated power management unit (PMU) combines nine digitally adjustable regulators, a fuel gauge, a 12-bit Low quiescent current: 5.1 A standby mode, including UVLO analog-to-digital converter (ADC), 2 kb of one time programmable 16-bit coulomb counter fuel gauge with integrated high-side (OTP) memory, anticounterfeit logic in a 42-ball, 2.880 mm current sensing resistor 2.980 mm WLCSP. The regulators include: 2 buck-boost, 1 buck 12-bit ADC to monitor battery voltage, output voltages, and regulator, 5 low dropout (LDO) regulators, and one low input LDO. junction temperature The ADP5320 meets demanding performance and board space Channels 1 and Channel 2: 150 mA low power buck-boost requirements for wearable applications. regulator The ADP5320 operates from a 1.8 V to 5.5 V input supply voltage Selective buck, boost, or buck-boost operation range, enabling the device for use with multiple types of battery Selective hysteresis or pulse-width modulation (PWM) mode inputs including: 2S/3S Zinc-air coin-cells or Li-poly/Li-ion batteries, Selective PWM frequency: 50 kHz to 225 kHz as well as other types of dc power sources. 2 programmable GPIOs for clock synchronization or fast stop The ADP5320 PMU fuel gauge includes a precision 16-bit coulomb switching input counter that integrates battery current flowing through the device. Channel 3: 150 mA low power buck regulator A 12-bit ADC is included to monitor battery voltage, output supply Channel 4 Through Channel 6, and Channel 8: 50 mA low noise voltages, and the junction temperature. Other features include a LDO, 1.65 V to 5.5 V input supply voltage range programmable sequencing engine and system fault recovery. Channel 7: 50 mA sink current LDO The ADP5320 PMU buck-boost regulators are high efficiency, step Channel 9: 50 mA, low noise LDO, 1.0 V to 1.9 V input supply up and step down regulators that operate at input voltages greater voltage range 2 than, less than, or equal to the regulated output voltage. All regula- I C interface with interrupt warning tors, including the six LDOs, are digitally programmable to meet 2 kb OTP memory different power requirements for many applications. Power-good monitor and watchdog power hard reset 2 The ADP5320 includes a 2-wire, I C-compatible, digital interface UVLO, peak current-limit protection, and TSD protection and is rated at the 10C to +70C operating junction temperature Integrated anticounterfeit logic module range. 42-ball, 0.40 mm pitch, 2.880 mm 2.980 mm WLCSP 10C to +70C operating junction temperature range APPLICATIONS Wearable medical applications Internet of Things (IoT) applications Disposable sensor devices Battery-powered devices For more information about the ADP5320, contact your local Analog Devices, Inc., sales office at ADP5320 analog.com.
