Texas Instruments · Gate Drivers · VSSOP-10-0.5mm

LM5102MMX from Texas Instruments, in a VSSOP-10-0.5mm. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD power_in Positive gate drive supply voltage; operating range 9V to 14V, must be decoupled to VSS using low ESR/ESL capacitor placed close to IC.
2 HB power_in High-side gate driver bootstrap rail; connect positive terminal of bootstrap capacitor here with voltage range VHS + 8V to VHS + 14V.
3 HO output High-side gate driver output; drives high-side MOSFET gate with 15-ns rise and fall time on 1000-pF loads, 25-ns maximum turn-off propagation delay.
4 HS power_in High-side MOSFET source connection; floating reference node for high-side driver with operating range -1V to 100V relative to VSS.
5 RT1 passive High-side rising edge delay programming resistor; resistor from RT1 to ground programs the leading edge delay of high-side gate driver output.
6 RT2 passive Low-side rising edge delay programming resistor; resistor from RT2 to ground programs the leading edge delay of low-side gate driver output.
7 HI input High-side driver control input with TTL-compatible thresholds; unused inputs must be tied to ground and not left open.
8 LI input Low-side driver control input with TTL-compatible thresholds; unused inputs must be tied to ground and not left open.
9 VSS power_in Ground return; all signals are referenced to this ground connection.
10 LO output Low-side gate driver output; drives low-side MOSFET gate with 15-ns rise and fall time on 1000-pF loads, 25-ns maximum turn-off propagation delay.
