Notes
1. When the pin voltage exceeds 70 V, the device functions asa power Zener diode, and limits the voltage.
2. Internally limited by thermal protection; switching point » 170 .
3. Up to VP = 18 V.
4. Latch-up test at Tj(max).
5. Machine model: equivalent to discharging a 200 pF capacitor through a 0 series resistor.
6. Human body model: equivalent to discharging a 100 pF capacitor through a 1.5 kseries resistor.



Description

The TDA8354Q is a power circuit for use in 90° and 110° colour deflection systems for 25 to 200 Hz field frequencies, and for 4 : 3 and 16 : 9 picture tubes. The IC contains a vertical deflection output circuit, operating as a high efficiency class G system. The full bridge output circuit allows DC coupling of the deflection coil in combination with single positive supply voltages.

The IC of the TDA8354Q is constructed in a Low Voltage DMOS (LVDMOS) process that combines bipolar, CMOS and DMOS devices. DMOS transistors are used in the output stage because of the absence of second breakdown.
