ITV4030 12A/15A Series
Surface Mount
Battery Protector Datasheet
Description
ITV4030 Series is a three terminals surface mountable battery
protector which is designed to against both overcurrent and
overvoltage (overcharging). A fuse element is embedded to cut off
the circuit when overcurrent issue happens. A heater is also
directly embedded under the fuse element, it will generate heat to
blow the fuse once overvoltage detected by IC or FET.
Features
Halogen Free
Surface Mount
Fast response
Protection for both

5 x Irated, power on 5 ms, power off 995 ms, 10000 cycles, No Melting
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 2mm*2oz copper traces, AWG18 covered wire, and 0.6mm glass epoxy PCBfor ITV4030 12A Series.
