The TPS22976 product family consists of two devices: TPS22976 and TPS22976N. 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 0.6 V to 5.7 V, and can support a maximum
continuous current of 6 A 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 TPS22976 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
TPS22976 also offers an optional integrated 230-Ω on-chip load resistor for quick output discharge
when the switch is turned off.
The TPS22976 is available in a small, space-saving 3-mm × 2-mm 14-SON package (DPU) with
integrated thermal pad allowing for high power dissipation. The device is characterized for
operation over the free-air temperature range of –40°C to 105°C.
