Power Management Integrated Circuits (PMICs) are electronic components used in electronic devices to provide power regulation and management. Gate Drivers, a type of PMIC, provide the necessary control signals required to drive high current devices, such as MOSFETS, IGBTs, or Relays, in order to activate or deactivate them. The MIC5015BM is a dual, low voltage, high current, monolithic Gate Driver developed by Micrel Inc. The MIC5015BM has a wide range of application fields, from portable applications to white goods and industrial electronics, and is capable of handling high currents of up to 4.5 A. The MIC5015BM is also designed for a wide range of operating voltages, supporting voltages from 2.6 to 15 volts.

The main features of the MIC5015BM include a fast switching time (<10 ns), low power losses (< 60 mW), and undervoltage/overvoltage protection. The MIC5015BM also supports a wide range of power supply configurations, such as dual 3.3V, dual 2.5V, dual 1.2V, or a combination of all three. The MIC5015BM likewise provides a high level of system protection, with thermal shutdown and short circuit protection.

The working principle of the MIC5015BM is based on the use of an N-channel and P-channel MOSFET as the power control elements. It uses an input voltage to control the gate of the MOSFET, allowing it to be switched on or off, depending on the input signal. The MIC5015BM also has a built-in transformer-isolated gate driver that can be used to provide even higher levels of power (up to 8A) to the gate of the MOSFET for increased switching speed. The MIC5015BM also has a Charge Pump built-in, which eliminates the need for an external capacitor, saving design time and components.

In summary, the MIC5015BM is a low voltage, high current, monolithic gate driver with a wide range of application fields and support for a wide range of operating voltages. It is capable of handling high currents of up to 4.5A, has a fast switching time (<10 ns), and provides a high level of system protection. It also has a built-in transformer-isolated gate driver and Charge Pump, eliminating the need for external components. The MIC5015BM is an ideal choice for any application that requires high current MOSFETs.
