Product Overview
TPS22919 is a Texas Instruments self-protected load switch for Power_Management designs. The device is supplied in an SC-70 (6) package with a 2.1 mm x 2.0 mm body size and the TPS22919DCK package option. Recommended input operation is 1.6 to 5.5 V, with a recommended output voltage range of 0 to 5.5 V.
The switch is rated for 1.5 A maximum continuous current and 2.5 A pulsed current for 2 ms at 2% duty cycle. Typical on-resistance is 89 mOhm at 5 V, 90 mOhm at 3.6 V, and 105 mOhm at 1.8 V. ON-state VIN quiescent current is 8 uA typical, while VIN shutdown current is 2 nA typical at 25°C.
Protection and control functions include output short protection, a 3 A short-circuit current limit condition, 2 us output short response time, thermal shutdown thresholds of 180°C rising and 145°C falling, and a quick output discharge path. The ON pin is an active-high control input that should not be left floating, while the QOD pin can be configured with an external resistor, tied to VOUT, or left floating to disable discharge.
