Texas Instruments TPS22995H-Q1 Automotive Load Switch
Texas Instruments TPS22995H-Q1 Automotive Load Switch incorporates a 19mΩ N-channel MOSFET that operates over an input voltage range of 0.8V to 5.5V with a maximum continuous current of 3A. The TPS22995H-Q1 is controlled by an on-and-off input (ON), capable of interfacing directly with low-voltage GPIO signals. The TPS22995H-Q1 provides a Quick Output Discharge when the switch is turned off, pulling the output voltage down to a known 0V state. Furthermore, the device offers an adjustable rise to limit inrush currents with high capacitive loads.
The pins of the TI TPS22995H-Q1 switch are resistant to high humidity conditions. This humidity feature allows the device to function with a 100kΩ short from any pin to GND or power. When the timing pin (RT) is affected by high humidity, timing is expected to stay within +/–20%.
The TPS22995H-Q1 is housed in a 2.8mm x 2.9mm, 0.5mm pitch, 6-pin SOT package and characterized for operation over the free-air temperature range of –40°C to +125°C.
