The maximum input voltage that can be applied to the TPS2226DBR is 5.5V, as specified in the datasheet. However, it's recommended to operate the device within the recommended input voltage range of 2.7V to 5.5V for optimal performance and reliability.
To ensure the TPS2226DBR switches on and off correctly, make sure to provide a clean and stable input voltage, and use a suitable pull-up resistor (typically 1kΩ to 10kΩ) on the EN pin. Also, ensure that the input voltage is within the recommended range and the device is operated within the specified temperature range.
The TPS2226DBR is a 2A switch, which means it can handle a maximum continuous current of 2A. However, the device can handle higher currents for short periods of time, up to 3A, as specified in the datasheet. It's essential to consider the device's thermal characteristics and ensure proper heat sinking to prevent overheating.
To minimize power consumption when the TPS2226DBR is in shutdown mode, ensure that the EN pin is pulled low (typically to GND) and the input voltage is removed. This will put the device in a low-power state, reducing quiescent current to typically less than 1μA.
No, the TPS2226DBR is a low-side switch, meaning it can only switch the ground connection of a load. It's not suitable for high-side switching applications. If you need a high-side switch, consider using a different device, such as the TPS229xx series.
