Product Description

The TPS28225D is a 8-pin High Frequency Sink Synchronous MOSFET Driver with adaptive dead-time control. This driver is optimized for use in variety of high-current one and multi-phase DC-to-DC converters. This is a solution that provides high efficiency, small size and low EMI emissions. The efficiency is achieved by up to 8.8V gate drive voltage, 14ns adaptive dead-time control, 14ns propagation delays and high-current 2A source and 4A sink drive capability. The 0.4R impedance for the lower gate driver holds the gate of power MOSFET below its threshold and ensures no shoot-through current at high dV/dt phase node transitions. The bootstrap capacitor charged by an internal diode allows use of N-channel MOSFETs in a half-bridge configuration. The TPS28225 features a 3-state PWM input compatible with all multi-phase controllers employing 3-state output feature. As long as the input stays within 3-state window for the 250-ns hold-off time, the driver switches both outputs low.
Drives two N-channel MOSFETs with 14ns adaptive dead time
Wide Power system train input voltage (3 up to 27V)
Wide input PWM signals (2.0 up to 13.2V amplitude)
Capable to drive MOSFETs with >=40A current per phase
High frequency operation (14ns propagation delay and 10ns rise/fall time allow FSW 2MHz)
Capable to propagate <30ns input PWM pulses
Low-side driver sink on-resistance (0.4R) prevents dV/dT related shoot-through current
3-state PWM input for power stage shutdown
Space saving enable (input) and power good (output) signals on same pin
Thermal shutdown
UVLO protection
Internal bootstrap diode
Green product and no Sb/Br
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
