SIP32434BDN-T1E4

The SIP32434A and SIP32434B are single-channel eFuse s that integrate multiple control and protection features, which provide increased controllability and reliability, wit h simplified designs and minimal external components. The SIP32434A and SIP32434B protect both power source s and downstream circuitry connected to the switch fro m overloads, short circuits, voltage surges, and excessiv e inrush currents. The output current limit can be set by a single external resistor. V_IN overvoltage protection and undervoltag e lockout threshold levels can be set with an external resisto r network. V_IN inrush current requirements can be set with a single external soft start capacitor. Upon switch-off due to latchable faults, the SIP32434A will latch the power switch off and the PGD will remain low. Th e switch can restart by resetting the EN or V_IN. The SIP32434 B will auto retry if there is no OTP or OVP fault. The retry dela y time is 32 times the soft start time set by the CSS. The switch is characterized for operation over a junctio n temperature range of -40 ℃ to +125 ℃.
