Dual High-Side TMOS Driver
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.
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 of
800 µs. The device is designed to withstand reverse polarity battery
and load dump transients, encountered in automotive applications.
Features
A single input controls the 33285 in driving two external high-side N-
An external charge capacitor provides access to the charge pump
