• Description: H-Bridge Gate Driver IC
• Manufacturer: FREESCALE [Freescale Semiconductor, Inc]

dt may result in perturbations of the high-side driver, thereby
forcing the driver into an OFF state. The addition of
capacitors C3 and C4, as shown in
dV/dt of the source line, consequently reducing driver
perturbation. Typical values for R3 / R4 and C3 / C4 are 10 
and 10 nF, respectively.
