- IQ = 13µA (typical, single channel) at VIN = VBIAS = 5V
- Control input threshold enables use of 1.2V, 1.8V, 2.5V, and 3.3V logic
- Configurable rise time
- Thermal shutdown
- Quick Output Discharge (QOD) (optional)
The TPS22996 product family consists of two devices: TPS22996 and TPS22996N. Each device is a dual-channel load switch with controlled turnon. The device contains two N-channel MOSFETs that can operate over an input voltage range of 0.6V to 5.5V, and can support a maximum continuous current of 4A per channel. Each switch is independently controlled by an on and off input (ON1 and ON2), which can interface directly with low-voltage control signals. The TPS22996 is capable of thermal shutdown when the junction temperature is above the threshold, turning the switch off. The switch turns on again when the junction temperature stabilizes to a safe range. The TPS22996 also offers an optional integrated 230Ω on-chip load resistor for quick output discharge when the switch is turned off.
The TPS22996 is available in a small, space-saving 2.1mm × 1.6mm 8-DRL package with leads to enable low cost manufacturing. The device is characterized for operation over the free-air temperature range of –40°C to 105°C.
