Littelfuse CH1B050P Pyro-fuse Trigger

Littelfuse CH1B050P Pyro-fuse Trigger uses open-loop Hall technology to detect an overcurrent condition and provide an output signal to activate a pyro module. The CH1B050P current sensor triggers the pyro module directly and offers a high fault current interruption capability. This fast and reliable Littelfuse circuit protection solution features low power consumption in a compact, lightweight design.
