-8-Lead 3x3 DFN The MCP14700 is a high-speed synchronous
MOSFET driver designed to optimally drive a high-side
and low-side N-Channel MOSFET. It is particularly well
suited for driving low-FOM MOSFETs, including
Microchip’s MCP87000 family of high-speed
MOSFETs. The MCP14700 has two PWM inputs to
allow independent control of the external N-Channel
MOSFETs. Since there is no internal cross conduction
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
1.2V on a falling PWM input signal. This makes the …
