TPS2114APW datasheet by Texas Instruments

TPS2114APW Frequently Asked Questions (FAQs)

• What is the maximum current that can be drawn from each channel?
  The maximum current that can be drawn from each channel of the TPS2114APW is 1A. However, it's recommended to limit the current to 0.5A per channel for optimal performance and to prevent overheating.
• How do I sequence the power-up of the two channels?
  The TPS2114APW has a built-in power-up sequencing feature. The device powers up the channels in a fixed sequence: Channel 1 powers up first, followed by Channel 2. The power-up sequence is controlled by the EN1 and EN2 pins, which can be tied together to enable both channels simultaneously.
• What is the purpose of the EN1 and EN2 pins?
  The EN1 and EN2 pins are active-high enable inputs that allow the user to control the power state of each channel independently. When EN1 or EN2 is low, the corresponding channel is turned off, and when it's high, the channel is turned on.
• How do I handle overcurrent protection (OCP) and short-circuit protection (SCP) in my design?
  The TPS2114APW has built-in OCP and SCP features. When an overcurrent or short-circuit condition is detected, the device will automatically limit the current or shut down the affected channel. The OCP and SCP thresholds can be adjusted using external resistors.
• What is the recommended layout and thermal management for the TPS2114APW?
  To ensure optimal performance and thermal management, it's recommended to follow the layout guidelines provided in the datasheet, including keeping the input and output capacitors close to the device, using a solid ground plane, and providing adequate thermal dissipation using a heat sink or thermal pad.
