Description
This evaluation circuit demonstrates theAPI9221 Lithium Ion Battery Charger. Thecharge and discharge cycle can be quickly andsimply demonstrated without a battery. Thecircuit includes a load consisting of anelectrolytic double layer capacitor bank of 5Farads to facilitate this demonstration. Theassembly also includes a set of resistive loads.There is a logic enable input, which disablescharging when pulled high. Manual links areprovided for these functions.The construction is a double-sided FR4 printedcircuit board, 95 x 60 x 1.6 mm with 1oz/sq ftcopper (35μm).
Features
- Dual Input – DC (6.8V OVP) and USB(5.4V OVP)
- Double layer capacitors on board todemonstrate battery charge cycle
- Load resistors on board up to 1A
- Programmable charging currents
- Ambient temperature range
- 40°C to +85°C
