SIP32434ADN-T1E4

The SIP32434A and SIP32434B are single channel eFuses protect both power sources and downstream circuitry from excessive inrush currents, overloads, short circuits, and overvoltage faults. They provide increased controllability and reliability with simplified designs with minimal external components. VIN overvoltage protection and undervoltage lockout threshold levels can be set with an external resistor network. VIN inrush current can be set with a soft start capacitor. The output current limit can be set by a resistor connected to ILIM pin. ILIM pin voltage can also serve as switch current reporting. Upon switch - off due to latchable faults, the SIP32434A will latch the power switch off and the PGD will remain low. The switch can restart by resetting the EN or VIN. The SIP32434B will auto retry if there is no OTP or OVP fault. The retry delay time is 32 times the soft start time set by the CSS. The switch is characterized for operation over a junction temperature range of - 40°C to +125°C
