MPPT IC for Solar PV System

Ultra-low power start-up: cold start under 400mV input voltage and 15μW input power
Boost regulator:
→MPPT configured through pins, configured as 70/75/85/90%
→MPPT open circuit voltage detected every 5 seconds
→input voltage range 150mV to 5V after startup.
Low-voltage LDO output:
→support a maximum load current of 20mA
→output voltage 1.2V/1.8V optional
→switch control through pins
High-voltage LDO output:
→maximum load current of 80mA
→output voltage optional/adjustable from 1.8V to 4.2V
→controlled by pins.
Battery management:
→configure overcharge and over discharge protection parameters for rechargeable batteries or supercapacitors
→prompt when the battery is exhausted; prompt when LDO is available
Battery switching:
→automatic switch to primary battery (battery exhausted)
→automatic switch to the energy storage battery (battery recover)
