The MIC4102 is a 100V half-bridge MOSFET driver with adaptive anti-shoot-through protection, designed to drive high- and low-side N-channel MOSFETs using a single PWM input. It is housed in an SOIC-8L package and operates with a junction temperature range of -40°C to +125°C. The device supports a bootstrap supply voltage up to 118V DC and a supply voltage of 9V to 16V, featuring an on-chip bootstrap diode, TTL-compatible input thresholds, and 2.5Ω pull-up and 1.5Ω pull-down output resistance. Propagation delays are 30ns typical, with rise and fall times of 10ns when driving a 1000pF load. It includes undervoltage protection on both high- and low-side supplies and a low-side drive disable pin for non-synchronous buck operation.
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.
