Test items Test purpose Notes
Temperature rise test Measure the temperature rise data of DUT under different currents Benchmark with competitors
Short circuit test Measure the ability of the DUT to withstand short-circuit current at different voltages (such as 4.2V, 6V7V) after turning it on. The higher the value, the better. Compare it with competitors for benchmark Short circuit time set to 260uS
BVtouch testing Simulate battery reverse connection test, the BVtouch voltage should be greater than the withstand voltage value, and the higher the value, the better Benchmark with competitors
UIS testing Test whether the DUT can safely turn off its ability under high currents. The higher the current that can be turned off, the more reliable it is The tested inductance is nH level small inductance
SOA testing Test the ability of DUT to withstand high power in the saturation zone, simulate the reliability of MOS withstanding V * l=power simultaneously during opening and closing periods. Under this working condition, the MOS tube operates in the amplification zone for a time of ms level Set the Vds voltage to a certain value (such as 5V) and gradually increase the Iss current until it fails. The larger the value, the higher the reliability
