NX30P0121UK 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. 2 Features and benefits Wide supply voltage range from 2.5V to 20V Switch maximum 3A continuous current 29V tolerance on both VIN and VOUT pin 54m (typical) Low ON resistance Adjustable overvoltage protection threshold, internal 14.5V VOUT OVLO Built in slew rate control for inrush current limit ISNS to monitor input current from VIN to VOUT Protection circuitry Over-temperature protection Overvoltage protection Undervoltage lockout ESD protection HBM ANSI/ESDA/JEDEC JS-001 Class 2 exceeds 2 kV CDM (JESD22-C101E) Specified from -40C to +85C 3 Applications Smartphone Tablet Other portable electronic devicesNXP Semiconductors NX30P0121UK High-voltage back-to-back OVP switch 4 Ordering information Table 1.Ordering information Type number Topside Package marking Name Description Version NX30P0121UK N21 WLCSP12 wafer level chip scale package 12 bumps 0.4 SOT1390-8 mm pitch 1.65 mm x 1.25 mm x 0.525 mm body (backside coating included) 4.1 Ordering options Table 2.Ordering options Type number Orderable part Package Packing method Minimum order Temperature number quantity NX30P0121UK NX30P0121UKZ WLCSP12 REEL 7 Q1 DP 4000 T = -40 C to +85 C amb CHIPS 5 Functional diagram VIN VOUT ISNS OVLO GND EN aaa-031747 Figure 1.Logic symbol NX30P0121 All information provided in this document is subject to legal disclaimers.
