Selection Guide

Choose the TPS2HC08-Q1 when you need a dual-channel smart high-side switch with a simple parallel interface and high current capability (up to 10A single channel). It is ideal for automotive body control, lighting, and actuator applications where SPI control is not required. If you need advanced diagnostics and SPI control, consider the TPS2HCS08-Q1, which offers I2T wire protection and low power mode. For higher current requirements, the TPS2HC10-Q1 provides 10A per channel but may have a different pinout. Cross-brand alternatives like the Infineon BTS7008-2EPA offer similar functionality but require a different package and layout, so they are not drop-in replacements. Always verify pin compatibility and electrical specifications before substitution.

Key Differentiators

  • Low on-resistance of 9.5mΩ (vs TPS2HCS08-Q1)
  • Parallel interface for simple control (vs TPS2HCS08-Q1)
  • Higher single-channel current capability (vs TPS2HCS08-Q1)

Design Notes

The TPS2HC08-Q1 can dissipate significant power when driving high currents. For example, at 10A with 9.5mΩ on-resistance, power dissipation is approximately 0.95W per channel. Ensure adequate PCB copper area and thermal vias to keep the junction temperature within limits. The VQFN-HR package has an exposed pad that must be soldered to a thermal land for optimal heat transfer.

Place a 100nF ceramic capacitor close to the VS pin and a 10µF bulk capacitor for transient handling. Route high-current paths with wide traces to minimize inductance and voltage drop. Follow the recommended layout in the datasheet to avoid parasitic coupling and ensure stable operation.

Do not exceed the absolute maximum ratings, especially input voltage and output current. Ensure the SPI interface is properly configured to avoid unintended switching. When driving inductive loads, use freewheeling diodes or ensure the device's internal clamping handles the back-EMF. Verify the thermal performance under worst-case conditions.
