- Schmitt-trigger input with hysteresis rejecting noisy gate drive signals and eliminating spurious switching in high-dv/dt environments
- Single-channel non-inverting driver topology compatible with direct MCU PWM output or deadtime controller ICs
- Wide input voltage compatibility from 4.5 V to 18 V supporting diverse gate drive power supply designs
- 8-pin PDIP package for easy through-hole prototyping of motor drives, DC-DC converters, and power inverters
Applications
The MCP1406-E/P is used in synchronous buck converters, half-bridge motor drivers, and resonant LLC converters where rapid MOSFET gate charging with peak currents up to 6 A reduces switching transition times and associated switching energy losses. Its Schmitt-trigger input makes it robust against ringing and common-mode noise in high-frequency inverter stages operating above 100 kHz. The device also serves as a buffer between low-current PWM controller outputs and high gate-charge MOSFETs in PV inverter, UPS, and industrial variable-frequency drive designs.

Frequently Asked Questions
How does MCP1406-E/P's 6 A peak drive current reduce MOSFET switching losses in a 100 kHz buck converter?
A MOSFET with 20 nC gate charge requires approximately 20 A to charge in 1 ns, but with a 6 A peak source from MCP1406-E/P, the gate charges in approximately 3.3 ns, limiting crossover time to well under 10 ns. At 100 kHz switching frequency, this fast transition reduces switching loss by roughly 30% compared to a 1 A gate driver, directly improving converter efficiency from approximately 90% to over 93% in a 10 A, 48 V buck stage.
For a half-bridge MOSFET driver design, can MCP1406-E/P drive the high-side switch directly?
MCP1406-E/P is specified as a high-side capable driver in a bootstrap configuration. However, it requires an external bootstrap diode and capacitor to supply the floating gate drive voltage above the switching node. For a 48 V half-bridge, a 100 nF bootstrap capacitor with a fast recovery diode (Vf below 0.5 V) provides adequate hold-up voltage for gate drive pulses up to 10 µs duration at duty cycles below 90%.
How does the Schmitt-trigger input of MCP1406-E/P improve noise immunity compared to a standard CMOS input driver?
The Schmitt-trigger input provides approximately 0.4 V to 1.5 V of hysteresis between the rising and falling input thresholds, preventing false triggering from high-frequency ringing on the PWM signal line. In a half-bridge layout with dv/dt rates above 10 V/ns, a standard CMOS input driver can misfire due to coupled noise below 100 mV, while the MCP1406-E/P Schmitt-trigger threshold rejects all signals below the lower hysteresis band, ensuring single clean transitions per PWM cycle.
In a solar micro-inverter design, what gate charge range of MOSFETs can MCP1406-E/P drive at 200 kHz?
At 200 kHz with 6 A peak drive current, MCP1406-E/P can charge a MOSFET gate in under 10 ns if the gate charge is below 60 nC. MOSFETs with gate charges up to 50 nC (such as IRF540 class devices) can be driven at 200 kHz with transition times below 8 ns, keeping switching losses manageable. For gate charges above 100 nC in high-current MOSFETs, a parallel configuration of two MCP1406 drivers providing 12 A peak is recommended.
How does MCP1406-E/P's propagation delay affect deadtime setting in a synchronous rectifier buck converter?
MCP1406-E/P has a propagation delay typically below 40 ns from input edge to output edge, and the rise and fall times of the gate drive output are below 20 ns at 1 nF gate capacitance. When setting deadtime in a synchronous buck controller, the deadtime register must account for the driver propagation delay plus the MOSFET turn-off time (typically 20–50 ns). A minimum safe deadtime of 80 ns to 120 ns prevents shoot-through in a 12 V synchronous buck at full load.
