TPS2095D datasheet by Texas Instruments

TPS2095D Frequently Asked Questions (FAQs)

• What is the maximum current that can be sourced by the TPS2095D?
  The TPS2095D can source up to 1.5A of current per channel, but it's recommended to limit it to 1A per channel for reliable operation.
• How do I ensure that the TPS2095D switches between channels quickly and efficiently?
  To ensure fast and efficient channel switching, make sure to use a low-ESR capacitor (e.g., ceramic or film capacitor) for the bypass capacitor (CBP) and keep the PCB layout clean and short.
• What is the purpose of the EN pin, and how do I use it?
  The EN (enable) pin is used to enable or disable the entire device. When EN is low, the device is in shutdown mode, and all channels are turned off. When EN is high, the device is enabled, and the channels operate normally.
• How do I handle overcurrent protection (OCP) and short-circuit protection (SCP) in my design?
  The TPS2095D has built-in OCP and SCP features. When an overcurrent or short-circuit condition is detected, the device will limit the current or shut down the channel to prevent damage. You can adjust the OCP threshold by setting the RSENSE resistor value.
• What is the recommended layout and routing for the TPS2095D to minimize EMI and noise?
  To minimize EMI and noise, keep the power traces short and wide, use a solid ground plane, and place the bypass capacitor (CBP) close to the device. Also, avoid routing sensitive signals near the power traces and use shielding or guard rings if necessary.
