TPS22917DBVR – 1V to 5.5V 2A 80mΩ Ultra-Low Leakage Load Switch – SOT-23-6 Package
The TPS22917x device is a small, single-channel load switch using a low leakage P-Channel MOSFET for minimum power loss. Advanced gate control design supports operating voltages as low as 1 V with minimal increase in ON-Resistance and power loss. The Rise and Fall times can be independently adjusted with external components for system-level optimizations. The timing capacitor (CT) and turn-on time can be adjusted to manage inrush current without adding unnecessary system delays. The output discharge resistance (QOD) can adjust the output fall time. Connect the QOD pin directly to the output for the fastest fall time or leave it open for the slowest fall time.
Features:
- Input operating voltage range (VIN): 1 V to 5.5 V
- Maximum continuous current (IMAX): 2 A
On-resistance (RON):
– 5 VIN = 80 mΩ (typical)
– 1.8 VIN = 120 mΩ (typical)
– 1 VIN = 220 mΩ (typical) - Ultra-low power consumption:
– ON state (IQ): 0.5 µA (typical)
– OFF state (ISD): 10 nA (typical) - Smart ON pin pulldown (RPD):
– ON ≥ VIH (ION): 10 nA (maximum)
– ON ≤ VIL (RPD): 750 kΩ (typical) - Adjustable turn ON limits inrush current (tON):
– 5-V tON = 100 μs at 72 mV/μs (CT = open)
– 5-V tON = 4000 μs at 2.3 mV/μs (CT = 1000 pF) - Adjustable output discharge and fall time:
– Optional QOD resistance ≥ 150 Ω (internal) - Always-ON true Reverse Current Blocking (RCB):
– Activation current (IRCB): –500 mA (typical)
– Reverse leakage (IIN,RCB): –1 µA (maximum)
