ADP5320BCBZ-1-R7

ADP5320 is a highly integrated power management unit (PMU) combines nine digitally adjustable regulators, a fuel gauge, a 12bit analogue-to-digital converter (ADC), 2Kb of one time programmable (OTP) memory, anti counter feit logic. The regulators include: 2× buck-boost, 1× buck regulator, 5× low dropout (LDO) regulators, and one low input LDO. This device meets demanding performance and board space requirements for wearable applications. It operates from a 1.8V to 5.5V 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. PMU fuel gauge includes a precision 16-bit coulomb counter that integrates battery current flowing through the device. It is used in application such as wearable medical applications, internet of things (IoT) applications, disposable sensor devices, battery-powered devices etc.
