The UBA2037T 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% duty cycle, the oscillator signal can be passed through a divider before being fed to the output drivers. The UBA2037TS is especially suitable for High Intensity Discharge (HID) lamp drivers for projectors and general lighting applications.

Features and benefits

  • Latch-up free and robust
  • Full bridge driver circuit
  • Integrated bootstrap diodes
  • 464 V integrated high voltage level shift function to drive HID lamps below GND
  • 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
  • Adaptive non-overlap

Applications

  • Commutator controller for HID lamps in general lighting applications
  • Commutator controller for HID lamps in projector applications
  • Driver (via external MOSFETs) for any load in a full-bridge configuration
