... Overcurrent protection with adjustable hiccup period. Undervoltage lockout and internal soft start Description The IR2086S is a self oscillating full-bridge controller and driver IC with 50% duty cycle ideally suited for 36V-75V full-bridge DC Bus Converters. Dead time can be controlled through proper selection of C from 50 to 200nsec. Internal soft start increases pulse width on power up and maintains equal pulse widths for the high and low outputs throughout the start up cycle ...

... IR2086S Absolute Maximum Ratings 12V 1000 pF, and T BIAS Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters are absolute voltages referenced to COM. All currents are defined positive into any lead. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions ...

... The value of the timing capacitor determines the amount of dead time between the two output drivers: lower the CT, shorter the dead time and vice versa not recommended to use a timing capacitor below 47pF. For best performance, keep the time components as close as possible to the IR2086S. Separated ground and Vdd traces to the timing components are encouraged. ...

... To prevent noise problem, a bypass ceramic capacitor connected to Vcc and COM1 / COM2 should be placed as close as possible to the IR2086S. IR2086S has an under voltage lookout feature for the IC bias supply, Vcc. The minimum voltage required on Vcc to make sure that IC will work within specifications must be higher than 8.5V (9.5V minimum Vcc is recommended to prevent asymmetrical gates signals on HO and LO pins that are expected when Vcc is between 7 ...
