The MCP14700-E/MF is a high-speed synchronous MOSFET Driver designed to optimally drive a high-side and low-side N-channel MOSFET. The MCP14700 has two PWM inputs to allow independent control of the external N-channel MOSFETs. Since there is no internal cross condition protection circuitry the external MOSFET dead time can be tightly controlled allowing for more efficient systems or unique motor control algorithms. The transition thresholds for the PWM inputs are typically 1.6V on a rising PWM input signal and typically 1V on a falling PWM input signal. This make the MCP14700 ideal suited for controllers that utilize 3.0V TTL/CMOS logic. The PWM inputs are internally pulled low.

• Ideally suited to drive low figure-of-merit (FOM) MOSFETs

• Input logic level threshold 3.0V TTL compatible
• Dual output MOSFET drive for synchronous applications
• 2A (typical) High peak output current
• Internal bootstrap blocking device
• +36V Boot pin maximum rating
• 45µA Typical low supply current
• High capacitive load drive capability - 3300pF in 10.0ns (typical)
• Input voltage under-voltage lockout protection

• Over-temperature protection
