3.5 A, 78 m

, 2.8 V to 23 V True Reverse Current Blocking eFuse

With Programmable Current Limit and OVP

OPERATION DESCRIPTION

The SIP32433A and SIP32433B are single-channel eFuses

that integrate multiple control and protection features,

which provide increased controllability and reliability, with

simplified designs and minimal external components.

The SIP32433A and SIP32433B protect both power sources

and downstream circuitry connected to the switch from

overloads, short circuits, voltage surges, and excessive

inrush currents.

The output current limit can be set by a single external

resistor. VIN overvoltage protection and undervoltage

lockout threshold levels can be set with an external resistor

network. VIN inrush current requirements can be set with a

single external soft start capacitor.

Upon switch-off due to latchable faults, the SIP32433A will

latch the power switch off and the PGD will remain low. The

switch can restart by resetting the EN or VIN. The SIP32433B

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.
