TCKE805 Series
TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TCKE805 Series
18 V, 5A eFuse IC with Adjustable Over Current Protection and Reverse
Blocking FET Control
The TCKE805 series are 18 V high input voltage Single Inputs－
Single Output eFuse IC. 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 control by an external capacitance, under voltage protection,
thermal shutdown and reverse current blocking by external MOSFET
control circuit.
Switch ON resistance is only 28 mΩ, high output current is up to
5.0A, and wide input voltage operation characteristics makes this
product ideal for power management applications such as in the power
supply circuit of hard disk drive and battery charging applications.
This device is available in 0.4mm pitch small package WSON10B
(3.0 mm x 3.0 mm, t: 0.7 mm (typ). Thus this devices is ideal for
various applications such as portable electronics that require
high-density boards. WSON10B
