3 Description
The TPS22976 product family consists of three
devices: TPS22976, TPS22976A 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, spacesaving
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.
