MIC4102 100V Half Bridge MOSFET Driver with Anti-Shoot Through Protection PRELIMINARY SPECIFICATIONS General Description Features The MIC4102 is a high frequency, 100V Half Bridge ? Drives high- and low-side N-Channel MOSFETs with MOSFET driver IC featuring internal anti-shoot-through single input protection. The low-side and high-side gate drivers are ? Adaptive anti-shoot-through protection controlled by a single input signal to the PWM pin. The ? Low side drive disable pin MIC4102 implements adaptive anti-shoot-through circuitry ? Bootstrap supply voltage to 118V DC to optimize the switching transitions for maximum efficiency. The single input control also reduces system ? Supply voltage up to 16V complexity and greatly simplifies the overall design. ? TTL input thresholds The MIC4102 also features a low-side drive disable pin. ? On-chip bootstrap diode This gives the MIC4102 the capability to operate in a non- ? Fast 30ns propagation times synchronous buck mode. This feature allows the MIC4102 ? Drives 1000pF load with 10ns rise and 6ns fall times to start up into applications where a bias voltage may ? Low power consumption already be present without pulling the output voltage down. ? Supply under-voltage protection Under-voltage protection on both the low-side and high- side supplies forces the outputs low. An on-chip boot-strap ? 2.5 ? pull up , 1.5 ? pull down output resistance diode eliminates the discrete diode required with other ? Space saving SOIC-8L package driver ICs. ? ?40 ?C to +125 ?C junction temperature range The MIC4102 is available in the SOIC-8L package with a junction operating range from ?40 ?C to +125 ?C.

PWM low signal makes high-side HO output low, and low-side LO output high. 6 LS Low-Side Disable. When pulled low, this control signal immediately terminates the low-side LO output drive. The low-side LO output drive will remain low until this signal is removed. HS drive is not affected by the LS signal. Here is the logic table: LS PWM LO HO 0 0 0 0 0 1 0 1 1 0 1 0 1 1 0 1 7 VSS Chip negative supply, generally will be grounded. 8 LO Low-Side Output. Connect to gate of Low-Side power MOSFET.
