1 Description
The TPS22966 device contains two N-channel MOSFETs that can operate over an input voltage range of
0.8V to 5.5 V and can support a maximum continuous current of up to 6-A per channel. Each switch is
independently controlled by an on/off input (ON1, ON2), which is capable of interfacing directly with low-
voltage GPIO control signals. In the TPS22966, a 260-Ω on-chip load resistor is added for quick output
discharge (QOD) when the switch is turned off. The rise time of the device is internally controlled in order
to avoid in-rush current and can be adjusted using a ceramic capacitor on the CTx pins. The TPS22966 is
available in a small, space-saving 2mm x 3mm 14-pin SON package with integrated thermal pad allowing
for high power dissipation.
The TPS22966 device is demonstrated using the TPS22966EVM-007 module. The TPS22966 Dual Load
Switch device can be configured in either a dual switch configuration or a parallel switch configuration
using the TPS22966EVM-007.
