CS3706

CS3706 CS3706 Dual Output Driver Description The CS3706 integrated circuit provides an interface between lowlevel TTL inputs and high-power switching devices such as power MOSFETs. A typical application is single-ended PWM control to pushpull power control conversion. The primary function of this device is to convert a bipolar single-ended low current digital input to a pair of totem pole outputs which can source or sink up to 1.5A. An internal flip-flop, driven by doublepulse suppression logic, can be enabled to provide single-ended to push-pull conversion. With the flipflop disabled, the outputs work in parallel for 3.0A capability. Protection functions are also included for pulse-by-pulse current limiting, automatic deadband control and thermal shutdown.
