The MIC4102 is a high frequency, 100V Half Bridge MOSFET driver IC featuring internal anti-shoot-through protection. The low-side and high-side gate drivers are controlled by a single input signal to the PWM pin. The MIC4102 implements adaptive anti-shoot-through circuitry to optimize the switching transitions for maximum efficiency. The single input control also reduces system complexity and greatly simplifies the overall design. The MIC4102 also features a low-side drive disable pin. This gives the MIC4102 the capability to operate in a non-synchronous buck mode. This feature allows the MIC4102 to start up into applications where a bias voltage may already be present without pulling the output voltage down. Under-voltage protection on both the low-side and high-side supplies forces the outputs low. An on-chip bootstrap diode eliminates the discrete diode required with other driver ICs. The MIC4102 is available in the SOIC-8L package with a junction operating range from -40°C to +125°C.
The MIC4100, MIC4101, MIC4103 and MIC4104 are a family of high-frequency, 100V MOSFET drivers. Each part contains a high-side and low-side driver and will drive many switching power supply topologies. Refer to the MIC4100/1 and MIC4103/4 specifications for detailed information. This evaluation board provides a platform for evaluating any of the drivers. The evaluation board schematic is shown in...
