10 Detailed Description
10.1 Overview
The TPS22963/64 is a single channel, 3-A load switch in a small, space saving CSP-6 package. These devices implement an N-channel MOSFET to provide an ultra-low On-resistance for a low voltage drop across the device. A controlled rise time is used in applications to limit the inrush current.

10.3 Feature Description
10.3.1 On/Off Control
The ON pin controls the state of the switch. It is an active “High” pin and has a low threshold making it capable of interfacing with low voltage GPIO control signals. It can be used with any microcontroller with 1.2 V, 1.8 V, 2.5 V, 3.3 V or 5.5 V GPIOs. Applying VIH on the ON pin will put the switch in the ON-state and VIL will put the switch in the OFF-state.
10.3.2 Quick Output Discharge
The TPS22964 includes the Quick Output Discharge (QOD) feature. When the switch is disabled, a discharge resistance with a typical value of 273Ω is connected between the output and ground. This resistance pulls down the output and prevents it from floating when the device is disabled.
