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 MCP14700 ideally suited for controllers that utilize 3.0V TTL/CMOS logic. The PWM inputs are internally pulled low ensuring the output drive signals are low if the inputs are floating. The HIGHDR and LOWDR peak source current capability of the MCP14700 device is typically 2A. While the HIGHDR can sink 2A peak typically, t...
