What are the key features of MCP1406T-E/SN?
- 6 A peak gate drive current with fast rise and fall times for rapid MOSFET switching in DC-DC converters operating at frequencies up to 1 MHz
- Schmitt trigger input with wide 4.5 V to 18 V supply range for noise-immune interfacing with PWM controllers in noisy switching power environments
- High-side capable single-channel MOSFET driver in compact 8-pin SOIC-8 (MS-012) package for easy integration into power stage PCB layouts
What is MCP1406T-E/SN used for?
The MCP1406T-E/SN is designed for driving N-channel or P-channel MOSFETs in synchronous buck converters, boost converters, and half-bridge motor drives where 6 A peak gate current is required to minimize switching losses at frequencies up to 1 MHz. Its Schmitt trigger input rejects noise on PWM control lines in high-dV/dt switching environments, making it suitable for motor controller power stages in industrial equipment. The 4.5 V to 18 V supply range and 8-pin SOIC footprint make it a versatile drop-in gate driver for power supply designs operating from 5 V, 12 V, or 15 V gate drive rails.

Frequently Asked Questions
What peak gate drive current can MCP1406T-E/SN deliver to a MOSFET gate in a switching power supply?
The MCP1406T-E/SN delivers 6 A peak gate drive current, enabling rapid charging and discharging of MOSFET gate capacitances in high-frequency DC-DC converters. At a gate charge of 50 nC, the 6 A peak current reduces transition time to approximately 8 ns, supporting switching frequencies up to 1 MHz with low switching losses in buck, boost, and full-bridge topologies.
How does the Schmitt trigger input on MCP1406T-E/SN improve performance in noisy gate drive circuits?
The Schmitt trigger input provides hysteresis, typically 0.3 V to 0.5 V, preventing false triggering caused by noise spikes or slow input edges on the PWM control signal. In a motor drive or DC-DC converter board with high dV/dt switching transitions of 10 V/ns or more, this hysteresis ensures the MCP1406T-E/SN only responds to legitimate PWM transitions, avoiding shoot-through or unintended MOSFET switching that could damage the power stage.
What supply voltage range does MCP1406T-E/SN support and which gate drive rails does it cover in common power designs?
The MCP1406T-E/SN operates from 4.5 V to 18 V supply voltage, covering standard gate drive rails of 5 V, 12 V, and 15 V used in industrial and consumer power designs. The 12 V gate drive rail is the most common for N-channel MOSFETs with 10 V gate threshold, while 15 V is used for SiC or high-threshold devices; the 18 V maximum allows margin for transients on unregulated gate drive supplies in motor inverter designs.
