Analog Devices Inc. MAX17701 Synchronous Step-Down Supercapacitor Charger Controller is part of the Himalaya series of voltage regulator ICs, power modules, and chargers. The Himalaya series enable cooler, smaller, and simpler power supply solutions. The MAX17701 is a high efficiency, high voltage 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. The MAX17701 regulates the no-load output voltage with ±1% accuracy after the supercapacitor is charged.
The MAX17701 has a safety timer (TMR) feature to set the maximum allowed constant current (CC) mode charging time. The MAX17701 also features an uncommitted comparator, which can be used to detect an output overvoltage event (OVI) and prevent the supercapacitor from overcharging.
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.
