UBA2035
Datasheet
General description
The UBA2035 is a high voltage monolithic Integrated Circuit (IC) manufactured in a High Voltage Silicon On Insulator (HVSOI) process. This circuit is designed for driving MOSFETs in a full bridge configuration. In addition, it features a disable function, an internal adjustable oscillator and an external clock input function with a high-voltage level shifter for driving the bridge. To guarantee an accurate 50 pct duty cycle, the oscillator signal can be passed through a divider before being fed to the output drivers.
The UBA2035 is especially suitable for High Intensity Discharge (HID) lamp drivers for projectors and general lighting applications for which a small non-overlap time is required.
Features
- Full bridge driver circuit
- Integrated bootstrap diodes
- 550 V series regulator input to make the internal supply
- 550 V maximum bridge voltage
- Accurate bridge disable function
- Input for start-up delay
- Adjustable oscillator frequency
- Selectable frequency divider
- Predefined bridge position during start-up
- A fixed non-overlap (< 200 ns)
