Typical values are for TA = 25°C. PARAMETER TEST CONDITIONS TA MIN TYP MAX UNIT (1) Applies to TPS22925B and TPS22925C only. VHYS ON pin hysteresis VIN = 3.6 V 25°C 86 mV VIN = 2.5 V 83 VIN = 1.8 V 82 VIN = 1.2 V 80 VIN = 1.0 V 79 VIN = 0.65 V 79 RPD (1) Output pull-down resistance VIN = VOUT = 3.6 V, VON = 0 V –40°C to 85°C 150 205 Ω –40°C to 105°C 215 (1) Turn-off time and fall time are dependent on the time constant at the load. For TPS22925BN and TPS22925CN, there is no QOD. The time constant is RL× CL. For TPS22925B and TPS22925C, internal pull-down resistor RPD is enabled when the switch is disabled. The time constant is (RPD || RL) × CL. 7.6 Switching Characteristics (1) over operating free-air temperature range (unless otherwise noted) VON = 3.6 V, RL = 10 Ω, CIN = 1 µF, CL = 0.1 µF,TA = 25°C PARAMETER TEST CONDITIONS TYP (TPS22925Bx) TYP (TPS22925Cx) UNIT tON Turn-on time VIN = 3.6 V 110 900 µs VIN = 1.8 V 94 730 VIN = 0.65 V 86 620 tOFF Turn-off time VIN = 3.6 V 3 3 µs VIN = 1.8 V 2.7 2.7 VIN = 0.65 V 10.9 10.9 tR Output voltage rise time VIN = 3.6 V 97 810 µs VIN = 1.8 V 61 520 VIN = 0.65 V 36 300 tF Output voltage fall time VIN = 3.6 V 2.2 2.2 µs VIN = 1.8 V 2.1 2.1 VIN = 0.65 V 3.6 3.6 tD Delay time VIN = 3.6 V 64 500 µs VIN = 1.8 V 66 490 VIN = 0.65 V 68 470 |
