MIC4104YM-TR

Power management Integrated Circuits (PMIC) are semiconductor devices used to convert and regulate electric power for a variety of electronic devices. Gate Drivers are PMICs used to control the opening and closing of switches, such as transistors and FETs, in order to control the current and voltage flow in a system. The MIC4104YM-TR is a low-cost Gate Driver designed to provide fast and efficient switching of Power MOSFETs in a wide range of applications.

The MIC4104YM-TR is a wide-body, 5 Volt low-side Gate Driver with integrated bootstrap circuit, designed to provide a fast turn-on and turn-off time. It is suitable for a range of applications such as power conversion, lighting, and motion control. The device is able to drive N-Channel and P-Channel Power MOSFETs with currents up to 50A, allowing it to be used in low voltage applications. The MIC4104YM-TR is capable of operating from 3V to 5V supplies and can switch frequencies up to 250kHz.

The MIC4104YM-TR features a built-in startup and shutdown sequence, which eliminates the need for external circuitry. It also features a high-side output that can be used to control a P-Channel MOSFET, allowing for the efficient control of dual MOSFETs without the need for an external driver. The gate pin is capable of driving both N-Channel and P-Channel MOSFETs from a voltage as low as 3.3V.

The MIC4104YM-TR is able to drive a wide range of Power MOSFETs, including those rated for up to 125A, and can operate up to an ambient temperature of +125 degrees Celsius. It also features an integrated voltage regulator and overvoltage protection, allowing it to be used in a wide range of applications. Additionally, the device features integrated undervoltage lockout and isolated ground to protect the switching circuits.

The MIC4104YM-TR is designed to operate with low transition times, meaning that the switching speed and power efficiency is not compromised by long transition times. The rise and fall times are typically 2µs, leading to increased efficiency and power savings. The device also features integrated charge pump circuitry, allowing it to operate efficiently even in applications with high switching frequencies.

The working principle of the MIC4104YM-TR Gate Driver is based on its input and output pins. When a high-voltage signal is applied to the Gate pin, it causes the Gate to switch from its idle state to its active state, allowing current to flow through the MOSFET. This change in state is known as the “gate turn-on” and the Gate Driver can quickly switch between the two states. When the input voltage is removed, the Gate returns to its idle state, this is referred to as the “gate turn-off”. This allows the Gate Driver to quickly switch between the two states, allowing it to efficiently manage and control the power flow.

In summary, the MIC4104YM-TR is a wide-body Gate Driver designed to provide fast and efficient switching of Power MOSFETs. It is suitable for a variety of applications such as power conversion, lighting, and motion control, and is capable of driving up to 125A. The integrated voltage regulator, overvoltage protection and charge pump circuitry ensure reliable and efficient operation even at high switching frequencies. The integrated startup and shutdown sequence and its ability to drive both N-Channel and P-Channel MOSFETs with low transition times make the MIC4104YM-TR ideal for a wide range of applications.
