The 1.2 A peak drive current charges the MOSFET gate capacitance quickly; for a typical 10 nC gate charge, the driver transitions the gate in under 10 ns, though the external gate resistor and PCB trace inductance will dominate the actual edge rate. ## Package and temperature grade — board-level constraints Housed in an 8-lead SOIC package with 1.27 mm pitch, the TC1428COA routes easily on a two-layer board — the supply and output pins are on opposite sides, so the power loop can be kept tight with a local bypass capacitor placed within 5 mm of the VDD and GND pins. Shipping in tube format, the devices are oriented for pick-and-place with the pin-1 indicator at the tube's orientation notch. ## Input logic flexibility — inverting and non-inverting Both inverting and non-inverting inputs are available on independent channels, so a single TC1428COA can drive one MOSFET with the same polarity as the PWM signal and a second with inverted polarity — useful for a synchronous buck where the high-side and low-side gates require complementary signals. The two channels are independent, meaning they can be driven from separate control signals with no cross-coupling — each channel's input is isolated from the other's switching activity.","metaTitle":"Microchip TC1428COA Low-Side Gate Driver, 1.2A, 8-SOIC","metaDescription":"Active production low-side MOSFET gate driver. 1.2A peak source/sink, 4.5-16V supply, inverting/non-inverting inputs. 8-SOIC package.
