Symbol Parameter Test Conditions (Note 5) Min Typ. Max Unit VUVLO Input UVLO VIN rising 2.35 2.65 V IQ Input quiescent current Above UVLO, IOUT = 0 85 125 µA IREV Reverse leakage current VIN = 0V, VOUT = 5V, IREV at VIN 0.01 0.10 µA RDS(ON) Switch on-resistance VIN = 5V, IOUT = 0.2A 100 250 350 m Ω ILIMIT Over-load current limit VIN = 5V, VOUT = 4V 0.3 0.4 0.5 A IOS Short-circuit current OUT shorted to ground 0.3 0.4 0.5 A IROCP Reverse-current trigger point VIN = 5.0V, VOUT = 5.2V 0.20 0.25 A TTRIG Deglitch time from reverse current trigger to MOSFET turn off (Note 6) 0.5 0.7 1.0 ms VOVP Output over-voltage trip point (Note 7) 5.3 5.6 V TOVP Debounce time from output over-voltage to MOSFET turn off 15 µs VREC Recovery after turn-off from ROCP and OVP 101% VIN TON Output turn-on time (Note 8) CL = 0.1µF, RLOAD = 20Ω (UVLO to 90% VOUT-NOM) 0.7 ms TSHDN Thermal shutdown threshold VIN = 2.7V to 5.2V 150 °C THYS Thermal shutdown hysteresis 20 °C θJA Thermal Resistance Junction-to-Ambient (Note 9) SOT23 215 oC/W SC59 255 oC/W Notes: 5. Pulse-testing techniques maintain junction temperature close to ambient temperature; thermal effects must be taken into account separately. 6. When reverse current triggers at IROCP = 0.20A, the reverse current is continuously clamped at IROCP for 0.7ms deglitch time until MOSFET is turned off. 7. During output over-voltage protection, the output draws approximately 60µA current. 8. Since the output turn-on slew rate is dependent on input supply slew rate, this limit is only applicable for input supply slew rate between VIN/0.2ms to VIN/1ms. 9. Device mounted on FR-4 substrate PCB, 2oz copper, with minimum recommended pad layout. |
