Microchip Technology MCP14700-E/SN

Description
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 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, the LOWDR can sink 3.5A peak typically. The low resistance pull-up and pull-down drive allow the MCP14700 to quickly transition a 3300 pF load in typically 10 ns. Bootstrapping for the high-side drive is internally implemented, which allows for a reduced system cost and design complexity.
The MCP14700 features undervoltage lockout (UVLO) with a typical hysteresis of 500 mV. Overtemperature protection with hysteresis is also featured on the device.
