The MIC4469ZWM-TR, a member of the MIC4400 family of parts from Micrel, Inc., is a gate driver IC designed for the control of large PMOS and NMOS power devices. The IC is pin and function compatible with other MIC4400PG family devices.
In addition to low loss, low cost, and high accuracy gate drive, the part also offers an adjustable dead time to accommodate a variety of applications. This feature also allows it to drive both PMOS and NMOS power transistors within the same design.
The MIC4469ZWM-TR is an offer-side gate driver, which means that the output of the part is actually connected to the gate of the power device. An integrated bootstrap diode across the lower power MOSFET of the power device and the gate driver output ensure proper operation when the upper power MOSFET is on.
The part features a wide operating voltage range of 10V to 28V. It also has a high-current output drive, up to 1.4A peak at 5V or 1A continuous at 5V. The integrated logic-level protection clamp reduces the risk of over-driving the power device gate input.
The MIC4469ZWM-TR is designed for a variety of applications, including synchronous buck converters, DC to DC converter controllers, and high-current MOSFET drivers. In particular, the part is suitable for use in synchronous buck control circuits for high-current applications, such as supplying power to power amplifiers, high-current LEDs, and RF power transistors.
The MIC4469ZWM-TR also offers a typical rise time of 250ns, a typical fall time of 200ns, and a typical propagation delay time of 395ns. This enables the part to be used in higher speed converter control applications.
The device\'s power supply connection includes over-voltage protection, and the logic-level logic protection clamp ensures robust operation by clamping the gate drive voltage to an appropriate level. This prevents over-driving of the power device gate input.
The MIC4469ZWM-TR also offers current limiting and thermal shutdown protection. With its thermal protection feature, the device shuts down in the event of an over-temperature condition. The device\'s current limit feature helps protect the part from short-circuits, thus ensuring long-term operation.
In summary, the MIC4469ZWM-TR is a cost-effective, high-accuracy, and high-performance gate driver designed for driving large high-current power devices. By offering a wide operating voltage range, high-current output drive, adjustable dead time, and various protection functions, the device is suitable for many demanding applications.
