SIMULATED BATTERY LOGIC TESTING DEVICE

摘要

A simulated battery test device and method that is capable of testing a battery charging circuit and logic circuit to determine proper operation. An operational amplifier is used that can both source and sink current to simulate the operation of the battery. A battery low signal can be generated using the simulated battery test device to test a battery charging circuit and logic circuit in a battery low condition. In addition, a battery open signal can be generated to test the battery charging and logic circuit in a battery open condition. Charging currents are detected to determine if currents fall within an acceptable range.
