EFP01 Energy Friendly PMIC provides complete system power and primary cell battery Coulomb counting for EFM32 and EFR32 devices

PublishTime： 2020-07-08 Article Source：Silicon Labs

Silicon Labs EFP01 Energy Friendly Power Management IC (PMIC) is an extremely flexible, highly-efficient, multi-output power management IC, providing complete system power and primary cell battery Coulomb counting for EFM32 and EFR32 devices. These devices operate over a wide input voltage range (0.8 to 5.5 V) with quiescent current as low as 150 nA. EFP01 provides three voltage output rails and four supply outputs – 1x buck/boost converter, 1x buck-only DC-DC converter + LDO, 1x LDO and 1x switched – delivering up to 94% efficiency.

·Supports Single alkaline, dual alkaline, single lithium and USB

·Ideal for ultra-low-power battery-powered IoT devices

EFP01 PMIC Common Specs

Voltage Output A (VOA)

·Output Voltage: 1.7 V to 5.2 V

·DCDC A can be configured in Buck/Boost, Buck-only, orBoost-only

·DCDC A output be combined with the VOC linear regulatorfor more efficient regulation as the input voltage approachesthe output voltage

·Firmware-programmable switched output (VOA_SW) allows complete powerdown of high leakage external circuitry in low power modes

Voltage Output B (VOB)

·Output Voltage:

0.8 V to 3.3 V (EFP0109/EFP0111)
0.8 V to 1.255 V (EFP0104/EFP0108)

·DCDC B can be used only in Buck configuration

·Dedicated internal linear regulator in parallel provides more efficient regulation as the input voltage approaches the output voltage

Voltage Output C (VOC)

·Output Voltage: 1.7 V to 3.3 V

·Linear regulator only

·Can be used either to create an independent third outputsupply or in conjunction with DCDC A

Coulomb Counter

·Lossless (i.e. no sense resistor) measurement of charge into the load

Communication & Control

·Fully configurable I2C

·Direct Mode supports fast transitions between energymodes

·IRQ pin to notify host processor

Ultra-low Quiescent Current

·150 nA with no outputs enabled

·Short-circuit tolerant outputs

·Under-voltage lock-out (UVLO) circuitry holds device in lowest power reset state when VDDB is below 1.2 V

·Over-temperature monitoring and IRQ assertion

Wide Operating Range

·0.8 V to 5.5 V input power supply

·-40 to 100 °C junction temperature

Package

·QFN20 3x3 mm
