Texas Instruments High-Performance Analog TPS28226DR

The TPS28226DR is a high-frequency synchronous MOSFET driver designed for multi-phase DC-to-DC converters, featuring adaptive dead-time control and 4-A sink capability. It is housed in an SOIC-8 package measuring 4.90mm × 3.91mm and operates with a gate drive voltage range of 4.5V to 8.8V. The device supports input PWM signals up to 13.2V amplitude and provides 14-ns propagation delay with 10-ns rise and fall times, enabling operation up to 2 MHz. It includes an internal bootstrap diode, 3-state PWM input for shutdown, undervoltage lockout, thermal shutdown, and a combined enable/power good pin. The lower driver has a typical sink on-resistance of 0.4Ω to prevent shoot-through current during high dV/dt transitions. The device is rated for operation from -40°C to 125°C and includes thermal protection with a shutdown threshold of 160°C and hysteresis down to 140°C.
