ROHM Semiconductor BD58020GW E-Fuse Protection IC
ROHM Semiconductor BD58020GW E-Fuse Protection IC is an overvoltage, overcurrent, and overtemperature protection IC. The BD58020GW has a built-in low ON-resistance of 16mΩ (typ.) N-ch FET, which immediately prevents damage to the downstream components when a fault condition occurs. The ROHM Semiconductor BD58020GW also features a temperature protection function for two external NTC thermistors, enabling monitoring of two different locations in an application. External or internal fixed resistors can set the overvoltage and overcurrent levels.
