Full bridge control IC for HID general lighting
7.6 Bridge disable
The bridge disable function can be used to switch off all the MOSFETs as soon as the
voltage on pin BD exceeds the bridge disable voltage VBD. The bridge disable function
overrules all the other states.
8. Limiting values
Table 4. Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134). All voltages are measured with respect to signal
ground (pin 14); positive currents flow into the chip. The voltage ratings are valid provided other ratings are not violated.
