P1405A

P1405A Over voltage protector Description The P1405A over-voltage protection device features an ultra-low 30mΩ (typical) on-resistance high current integrated N-MOSFET which actively protects low-voltage systems from voltage supply faults up to +32VDC. An input voltage exceeding the over-voltage threshold will cause the internal MOSFET to turn off, preventing excessive voltage from damaging downstream devices. P1405A has thermal protection at 140°C The P1405A is available in a RoHS and Green compliant DFN2x2-6L package. VIN VBUS VOUT VBUSOUT 1uF PUDN 1uF P1405A GND Figure 1.
