TPS51604DSGR

Texas Instruments · Gate Drivers · WSON-8-EP(2x2)

TPS51604DSGR from Texas Instruments, in a WSON-8-EP(2x2). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 BST input High-side N-channel FET bootstrap voltage input; power supply for high-side driver; voltage range -0.3 V to 35 V (transient to 38 V <20 ns).
2 PWM input PWM input with tri-state gate driver control; tri-state window 1.3-2.0 V disables both output drivers for low-power mode; voltage range -0.3 V to 6 V.
3 SKIP input Mode selection input with tri-state capability; low enables zero-crossing detection (DCM mode), high disables (FCCM mode), tri-state enables very-low-power mode; voltage range -0.3 V to 6 V.
4 VDD power_in 5-V power supply input for driver IC; recommended operating voltage 4.5-5.5 V; decouple to GND with ≥1 µF ceramic capacitor.
5 DRVL output Synchronous low-side N-channel gate drive output; drives low-side MOSFET gate with rise time 15 ns and fall time 10 ns into 3.3 nF load; voltage range -0.3 V to 6 V.
6 GND power_in Synchronous low-side N-channel gate drive return and device reference ground; tie thermal pad to system GND plane with multiple vias for thermal performance.
7 SW bidirectional High-side N-channel gate drive return and zero-crossing sense input; detects inductor current zero-crossing for DCM operation; voltage range -1 V to 28 V.
8 DRVH output High-side N-channel gate drive output; drives high-side MOSFET gate with rise time 30 ns and fall time 8 ns into 3.3 nF load; voltage range -0.3 V to 6 V (transient to 38 V).
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
