Product Overview
LTC3625 is a programmable supercapacitor charger. Automatic cell balancing prevents overvoltage damage to either supercapacitor while maximizing charge rate. No balancing resistors are required. High efficiency, high charging current, low quiescent current and low minimum external parts count (one inductor, one bypass capacitor at VIN and one programming resistor) make the device ideally suited for small form factor backup or high peak power systems. Charging current/maximum input current level is programmed with an external resistor. When the input supply is removed and/or the EN pin is low, this device automatically enter a low current state, drawing less than 1µA from the supercapacitors. It is used in applications such as servers, RAID systems, mass storage, high current backup supplies, solid state hard drives, wireless power meters, high peak power boosted supplies etc.
- Input voltage range is 2.7V to 5.5V
- Selectable 2V/2.25V regulation per cell
- Input sleep current is 23µA typ at (VIN = 5.5V, VOUT = 5.4V)
- Input operating current is 135µA typ at (CTL = VIN, VMID = 1.5V, VOUT = 2.5V, boost only)
- VOUT sleep current is 1µA typ at (VOUT = 5.4V, VIN = 5.5V, EN = VIN)
- Operating junction temperature is -40°C to 125°C
- Package style is 12-lead plastic DFN
