Battery Protector Datasheet
ITV5432 30A Series
Surface Mount
Description
ITV5432 Series is a chip type surface mountable device that can
protect against both overcurrent and overcharging. It comprises a
fuse element to ensure stable operation under normal electrical
current and to cut off the current when overcurrent occurs. It also
comprises a resistive heating element that could be used in
combination with a voltage detecting means, such as IC and FET.
When overvoltage is detected, the heating element is electrically
excited to generate heat to blow the fuse element to achieve
overvoltage protection.

In operation voltage range, the fusing time is <1min.
Notes:
Irated = Current carrying capacity that is measured at 40°C thermal equilibrium condition
Ibreak = The current that the fuse element is able to interrupt
Vmax = The maximum voltage that can be cut off by fuse
VOP = Range of operation voltage
Rheater = The resistance of the heating element
Rfuse = The resistance of the fuse element
Cells in series = Number of battery cells connected in series in the circuit for ITV device to protect.
• Value specified is determined by using the PWB with 29.4mm*2oz copper traces, AWG10 covered wire, and 0.6mm glass epoxy PCB.
