开关 IC - 各种 DIODE BRIDGE w/OVP 100V, 240mA
Description
100V Diode Bridge with an integrated Over-Voltage Protection OVP thyristor uses Clare"s High Voltage SOI technology.
The CPC7556N integrated diode bridge offers protection from high voltage transients by means of an adjustable voltage clamp. The clamp performs two actions, first to limit the voltage across the diode bridge rectified outputs to a value determined by external resistors and the gate voltage and second to fully discharge the V+to V outputs when the Gate’s trigger threshold is exceeded during the voltage limiting function. The rectified outputs are discharged as a result of the voltage fold-back function of the OVP device. Voltage fold back of the OVP circuit will continue until the current through the protector falls below the hold current threshold.
Terminating the gate to V_ will disable the clamp voltage feature up to the thyristor’s off state voltage.
