It is qualified to AEC-Q100 Grade 1, meaning it is specified and tested for the -40°C to +125°C junction temperature range required in under-hood and chassis-mounted automotive electronics. The driver accepts a 4.5V to 5.5V supply rail, which is the bias voltage for the internal logic and the low-side gate drive. The high-side driver uses a bootstrap supply with an absolute maximum rating of 35V on the BST pin, so the converter's input voltage plus the bootstrap charging voltage must stay below that ceiling. ## Switching speed and dead-time budget The typical rise time is 30ns and the fall time is 8ns into the specified load. This asymmetric slew rate means the low-side MOSFET turns off faster than the high-side turns on, which helps prevent shoot-through but also sets a minimum dead-time the PWM controller must enforce. The controller's dead-time setting should exceed the turn-off propagation delay plus the fall time to guarantee break-before-make. The non-inverting input type means a logic high on the PWM input drives the high-side gate on; a logic low drives the low-side gate on. ## Package and thermal design The device is housed in an 8-WSON package with a 2x2mm body and an exposed thermal pad (8-WFDFN). The supplier device package is designated 8-WSON (2x2). A layout that skips the thermal pad connection will raise the junction temperature above the 125°C limit under continuous high-frequency switching. Surface-mount assembly with the tape-and-reel or cut-tape packaging options.","metaTitle":"TPS51604QDSGRQ1 Gate Driver, Half-Bridge, 8-WSON, AEC-Q100","metaDescription":"Texas Instruments TPS51604QDSGRQ1 automotive half-bridge gate driver, 4.5V-5.5V supply, 30ns rise/8ns fall, 8-WSON package.
