The MCP19214T-E/MQ is the first of its kind in a new generation of advanced, energy-efficient switching controllers with integrated gate drivers. It is a turn-key solution that integrates all the power circuit components needed to drive an efficient DC-DC controller, including a gate driver, voltage regulator, and current sense amplifier. This highly efficient design reduces power losses, decreases heat generation, and improves overall energy efficiency. The MCP19214T-E/MQ is the perfect fit for a multitude of power management applications, such as voltage regulation, integrating charging systems, and powering LEDs.

The MCP19214T-E/MQ uses a Pulse Width Modulation (PWM) control scheme to provide precision voltage regulation. It integrates four controlled switches and a reference voltage to generate a PWM signal. The PWM signal is then used to control the duty cycle of the MCP19214T-E/MQ’s switches, allowing for efficient management of power levels. The MCP19214T-E/MQ has two dedicated outputs to drive high-side and low-side power switches. The high-side switch provides output current to the load, while the low-side switch is used to discharge the load current.

The MCP19214T-E/MQ integrates four switches to provide a high-resolution level-shift signal, which is then used by the integrated gate driver to control the switch. This level-shift signal is generated by comparing the voltage applied to the control pins to the reference voltage. The reference voltage is adjustable and can be set using the programmable gain control (PGC) pins. The threshold voltage is independent of the power supply voltage, allowing the MCP19214T-E/MQ to be used in a wide range of operating voltages.

The MCP19214T-E/MQ also has integrated current sensing and protection features that help protect the device from overcurrent and over-voltage conditions. The integrated current sense amplifier monitors the load current and can limit the Ipeak and duty cycle of the load. The protection features also include an adjustable current limit, an over-voltage protection, and an under-voltage lockout (UVLO) protection. This combination of safety features makes the MCP19214T-E/MQ an ideal choice for applications where safety and reliability are paramount.

The MCP19214T-E/MQ is a very powerful and efficient DC-DC switching controller that is suitable for a wide range of power management applications. Its integrated gate driver, voltage regulator, and current sense amplifier enable efficient and reliable control of DC-DC converters. The adjustable reference voltage and integrated current sensing and protection features make the MCP19214T-E/MQ ideal for applications that require precision voltage regulation and reliable current limit operation.
