Energy Friendly Power Management for IoT Devices

An Ultra-low Power PMIC for IoT products. Optimised for sleepy devices, yet robust enough to cater to the peaky demands of a wireless transmitter. With a Coulomb Counter for measuring battery capacity & health included.

This PMIC offers a complementary solution to powering IoT centric products. With a mix of ultra-low quiescent current (150nA) while asleep, and switching on quickly to power short range wireless products (Bluetooth, Zigbee, Thread, Z-Wave, etc.). With the incorporated Coulomb Counter, you’ll always know your remaining battery capacity.

Advantages of this PMIC

• Wide input Range (0.8V – 5.5V)

• Three independent, configurable Voltage Rails

• Coulomb Counter for lossless operation (no sense resistor)

• Support for multiple battery chemistry

The EFP01 is a dedicated PMIC specifically targeting the unique demands of IoT applications. Silicon Labs is a respected leader in the Home Automation space, and understands intimately the unique needs of this sector.
