Super Capacitor Charging and Discharging Power
XYH series high-precision bidirectional DC power supply is a bidirectional charging and discharging device. It adopts two-stage conversion
After the supercapacitor is charged, the device regulates the no-load output voltage with ±1% accuracy. The output voltage is programmable from 1.25V up to (V DCIN - 2.1V). The MAX17701 supercapacitor charger controller is designed to provide a holistic application solution requiring backup energy storage with a precise charging capability.
To charge a supercapacitor, there are two major options: charging or discharging at a constant cell voltage to record the cell current change with time, and charging or discharging at a constant current to record that cell voltage change with time.
The MAX17701 is a high efficiency, high voltage, Himalaya synchronous, step-down, supercapacitor charger controller designed to operate over an input-voltage range of a 4.5V to 60V. The MAX17701 operates over a -40°C to +125°C industrial temperature range and charges a supercapacitor with a ±4% accurate constant current.
ADI MAX17701 supercapacitor charger controller is designed to provide a holistic application solution requiring backup energy storage with a precise charging capability. The MAX17701 is offered in a 24-pin 4mm x 4mm TQFN package with an exposed pad. Provides constant current (CC) mode and constant voltage (CV) modes to charge supercapacitors.
