The LM5134 is a high-speed single low-side driver capable of sinking and sourcing 7.6-A and 4.5-A peak currents. The LM5134 has inverting and noninverting inputs that give the user greater flexibility in controlling the FET. The LM5134 features one main output, OUT, and an extra gate drive output, PILOT. The PILOT pin logic is complementary to the OUT pin, and can be used to drive a small MOSFET located close to the main power FET. This configuration minimizes the turnoff loop and reduces the consequent parasitic inductance. It is particularly useful for driving high-speed FETs or multiple FETs in parallel. The LM5134 is available in the 6-pin
SOT-23 package and the 6-pin WSON package with an exposed pad to aid thermal dissipation.

---|---|---|---|---|
NAME | NO. | |||
VDD | 1 | — | Gate drive supply | Locally decouple to VSS using low ESR/ESL capacitor located as close as possible to the IC. |
PILOT | 2 | O | Gate drive output for an external turnoff FET | Connect to the gate of a small turnoff MOSFET with a short, low inductance path. The turnoff FET provides a local turnoff path. |
OUT | 3 | O | Gate drive output for the power FET | Connect to the gate of the power FET with a short, low inductance path. A gate resistor can be used to eliminate potential gate oscillations. |
VSS | 4 | — | Ground | All signals are referenced to this ground. |
INB | 5 | I | Inverting logic input | Connect to VSS when not used. |
IN | 6 | I | Non-inverting logic input | Connect to VDD when not used. |
EP | EP | — | Exposed Pad | It is recommended that the exposed pad on the bottom of the package be soldered to ground plane on the PC board, and that ground plane extend out from beneath the IC to help dissipate heat. |
