The TCKE8xx series is 18 V high input voltage Single Input

Single

Output eFuse ICs . It can be used as a reusable fuse, and includes

protection features like adjustable over current limit by an external

resistor short circuit protection, over voltage clamp , adjustable slew

rete c ontrol by an external capacitance, under v oltag e p rotection,

t hermal s hutdown and r everse current b locking by external MOS FET

c ontrol circuit

S

witch ON resistance is only 2 8 mΩ (typ ..)), high output current is up

to 5.0 A and wide input voltage operation characteristics makes this

series ideal for power manag ement applications such as in the power

supply circuit of h ard disk drive and b attery c harg ing applications.

This series

is available in 0. 5 m m pitch small package WSON10B

(3.0 mm x 3.0 mm, t: 0.7 mm (typ Thus t his series is ideal for

various application s such as portable electronics that req uire

high density soldering
