MIC4426BM

The MIC4426BM is a tiny monolithic Power Management Integrated Circuit (PMIC) that is versatile and suitable for a vast range of applications and products. It is a Gate Driver Device from the PMIC family, which is ideal for providing optimal performance during voltage and current operations. The MIC4426BM is a two channel product with two independent Gate Drivers for highly efficient and powerful functioning. This PMIC device is used for driving IGBTs, MOSFETs, relays and other control circuits. The MIC4426BM can support both high and low level drive circuits with up to 10 A peak current bearings and a rise time of 110 ns. It is also designed with reverse motor drive (RMD) circuits and provides a simplified connection design with 3 status pins. The MIC4426BM is small yet powerful and is easy to install into a system.

The MIC4426BM is an effective Gate Driver Device that is widely used in many applications. It is particularly suitable for driving pulse width modulation (PWM) switching power converters including AC-DC, DC-DC, full-bridge mode and half-bridge mode. This PMIC is also widely utilized in a range of power control circuits such as switch mode power supplies (SMPS) and DC-DC converters. This device is also widely used in solar inverters, current or voltage regulators, battery chargers, motor drives and industrial automation. Additionally, the MIC4426BM is also often found in lightning systems, light dimming systems, uninterruptible power supplies (UPS), electric vehicle charging, digital signage and consumer electronics.

The MIC4426BM works on a symmetric drive principle and is designed to derive a full rail-to-rail voltage drive signal. This PMIC is designed to ensure optimal responses even during high temperatures and its signal input resolution is approximately 10 A to 20 A per volt. It also features a wide signal common-mode range of 200 V and a total power supply up to 24 V. The MIC4426BM includes two integrated production boost circuits for efficient control and thermal management, allowing reliable current sensor designs with a low voltage bias.

The MIC4426BM also includes two protected functions called either Driver Overcurrent or Overvoltage Protection (DOCP or OVP). The DOCP is designed to protect the PMIC from shorts or overcurrents and the OVP is designed to protect the power supply from overvoltages and transients. Both the DOCP and OVP can be individually enabled or disabled. Additionally, this PMIC also supports an adjustable hysteresis function to control the current sensing level, thereby ensuring accurate voltage sensing. The MIC4426BM also supports a wide range of gate drive signals including gate turn-off signals, linear drive signals and pulse modulation signals.

Overall, the MIC4426BM is an effective, powerful and efficient Gate Driver Device that is perfect for a range of applications such as PWM switching power converters, SMPS, DC-DC converters, solar inverters, battery chargers, motor drives, lightning systems, and many other control circuits. This PMIC device is suitable for both high and low level drive circuits and is designed with reverse motor drive (RMD) circuits. Additionally, this device supports adjustable hysteresis and DOCP/OVP protection and is also designed with two integrated production boost circuits for optimal current sensor performance with low voltage bias.
