The device features a low on-resistance of 0.80 Ohm maximum at VGS=-10V and 1.10 Ohm at VGS=-4.5V. The ultra-low threshold voltage (VGS(th) max = -1.0V) enables direct drive from 2.5V to 3V logic supplies, making it ideal for single-cell Li-Ion battery switching. The -20V drain-source rating provides adequate margin for 3V to 12V battery bus applications. The compact SOT-23 package minimizes board space in portable designs. The device is suitable for load switching, battery disconnect, and power routing in cell phones, PDAs, and other battery-operated equipment.","working_principle":"The NTR1P02LT1G is a P-channel enhancement-mode MOSFET using onsemi's planar stripe DMOS technology. (1) P-Channel Enhancement: The device is normally off (no channel at VGS=0). When VGS is pulled below the threshold (negative), an inversion layer forms under the gate oxide, creating a conduction channel between source and drain. The very low threshold (-0.4 to -1.0V) means that only a small gate drive is needed to turn the device on. (2) Low RDS(on): The planar stripe DMOS cell geometry provides low specific on-resistance. At VGS=-4.5V (typical 3.3V system gate drive), RDS(on) is only 1.10 Ohm maximum, resulting in low conduction losses at the rated 0.4A drain current (P = I2R = 0.16 x 1.1 = 0.18W). (3) Logic-Level Drive: With VGS(th) as low as -0.4V, the MOSFET can be driven from 2.5V logic. At VGS=-2.5V, the device provides sufficient overdrive for many low-current switching applications.","pin_description":"
