MIC4428BM-TR

The MIC4428BM-TR is an advanced power management integrated circuit (PMIC) in the increasingly popular family of gate drivers. It is specifically designed to interface with 2-A, 2-MOSFETs for power-switching purposes. This high-performance PMIC is a safe and reliable choice for use in various industrial and commercial applications.

The non-reactive package of the MIC4428BM-TR helps prevent disturbances while operating. It is also equipped with features such as current limiting and thermal shutdown. This provides increased safety and robustness in all types of applications.

The MIC4428BM-TR is suitable for applications such as battery powered equipment, automotive, motor control and domestic appliances. Its versatility makes it a great fit for any environment where power-switching is involved. As a low side driver, it can provide exceptional performance in switched mode power supplies and portable battery-powered systems.

The working principle of the MIC4428BM-TR is quite simple. It is a dual-channel gate driver with independent outputs. Each output is capable of driving up to 2 A at 5 V with the capability of sinking up to 6 A at the same voltage. Each output is protected against over-current and over-temperature conditions. It is operated both actively and passively, with a minimum on-time of 10 ns. The device is also specified to operate in a wide temperature range from -40 to +125 degrees Celsius.

The MIC4428BM-TR operates with a 5V input voltage and a 9V/11V output voltage. It is capable of handling up to a 12A load current. The gate charge is 13nC and the gate resistance is 7mΩ (typical). The device is further protected against in-rush current by monitoring the primary currents of each of its two outputs.

The MIC4428BM-TR is the ideal choice for applications requiring reliable and fast output power switching. Its lower power consumption, along with its robust protection features, make it a great fit for low-power applications and those requiring operation in extreme environments. The high-performance features and simple working principle of this PMIC offer great value for money.
