High-voltage back-to-back OVP switch

Rev. 1.0 — 19 June 2019

Product data sheet

1 General description

The NX30P0121UK is an advanced 3A unidirectional power switch. It includes

Undervoltage Lockout (UVLO), Overvoltage Lockout (OVLO) in VOUT, OVLO adjustable

pin and over-temperature protection circuits. It is designed to automatically isolate the

power switch terminals when a fault condition occurs. Both VIN and VOUT pins have 29V

tolerance in shutdown mode.

The device has a default internal 14.5V overvoltage protection threshold in VOUT and

adjustable OVP threshold by resistor divider from VOUT. ISNS pin is current source

output proportional to input current from VIN to VOUT when device is enabled.

The device is enabled by external EN pin. When EN pin is driven LOW, the device is in

shutdown mode where all internal circuitries are off and OVP switch is off. When EN pin

is driven HIGH and VIN is valid, the OVP switch soft starts after VIN debounce time to

limit the inrush current.

NX30P0121UK is offered in a small 12 bumps, 1.65 x 1.25 x 0.525 mm WLCSP package.
