Power Management IC - Gate Drivers

Power management integrated circuits (PMICs) gate drivers allow fast, convenient and efficient switching of power semiconductor devices including MOSFETs, IGBTs and thyristors. The MAX15492GTA+T from Maxim Integrated uses advanced digital circuitry to provide gated current and/or voltage drive for small-signal devices. This IC offers two independent control channels for driving independent gates or for combining gates into one or two high-side gate drives.

MAX15492GTA+T Features and Benefits

The MAX15492GTA+T provides the following features and benefits:

• Two independent control channels for driving independent gates
• High-side gate drive current up to 500mA
• Over-current and thermal protection
• Operating voltage ranging from 4.5V to 18V
• Compact, space-saving 8-pin package

MAX15492GTA+T Application Fields and Working Principles

The MAX15492GTA+T is suitable for a wide range of applications including motor control, robotics, and other power conversion, as well as industrial and automotive applications. Its low cost, small package, and integrated protection make it invaluable for systems engineers looking to reduce design and manufacturing costs.

The MAX15492GTA+T has two independent control channels, one each for controlling a high-side gate and a low-side gate. The high-side gate control channel uses a sinking current driver to switch the gate. The driver is limited by an adjustable current set point, with over-current protection. The low-side gate control channel has asymmetric output levels, with both active-high and active-low outputs, making it suitable for driving various kinds of gates.

The MAX15492GTA+T also has integrated over-temperature protection. The temperature is monitored by an internal temperature sensor, and a resistance-compensated comparator monitors the temperature. If the temperature exceeds the set point, the driver reduces the gate-driving current until the temperature is within a safe range.

The MAX15492GTA+T also has short-circuit protection, which is enabled by an external resistor. When the output current exceeds the current limit, the device disables the output so it can be safely restablished.

Conclusion

The MAX15492GTA+T is an advanced power management IC gate driver that offers reliability, small-size, and integration with digital circuitry. It features two independent control channels for independent and combined gate drives. The integrated protection features provide enhanced system reliability. This power management IC is ideal for applications in motor control, robotics, industrial, and automotive applications.
