MIC4102 .. 100V Half Bridge MOSFET Driver with Anti-Shoot Through Protection PRELIMINARY SPECIFICATIONS General Description 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 plexity 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 nonsynchronous 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 highside supplies forces the outputs low. An on-chip boot-strap 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. Data sheets and support documentation can be found on Micrel’s web site at .micrel..
