Dual High-Side TMOS Driver
A single input controls the 33285 in driving two external high-side NChannel 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.
An external charge capacitor provides access to the charge pump output.
Both external FETs are protected against inductive load transients by separate internal source-to-gate dynamic clamps.
The power FETs are protected by the 33285 with short-circuit delay time o...
