Dual High-Side TMOS Driver

A single input controls the 33285 in driving two external high-side N-Channel TMOS power FETs controlling incandescent or inductive loads. Pulse Width Modulated (PWM) input control to 1.0 kHz is possible. The 33285 contains a common internal charge pump used to enhance the Gate voltage of both FETs.
