ISO5851 IGBT Gate Driver

By Texas Instruments 73

ISO5851 IGBT Gate Driver

Texas Instruments' ISO5851 is a 5.7 kVRMS, reinforced isolated gate driver for IGBTs and MOSFETs with 2.5 A source and 5 A sink current. The input side operates from a single 3 V to 5.5 V supply. The output side allows for a supply range from minimum 15 V to maximum 30 V. Two complementary CMOS inputs control the output state of the gate driver. The short propagation time of 76 ns assures accurate control of the output stage.

The ISO5851 is available in a 16-pin SOIC package. Device operation is specified over a temperature range from -40°C to 125°C ambient.

Features
  • 2.5 A peak source and 5 A peak sink currents
  • Short propagation delay: 76 ns (typical), 110 ns (max)
  • 2 A active miller clamp
  • Output short-circuit clamp
  • Fault alarm upon desaturation detection is signaled on FLT and reset through RST
  • Input and output under voltage lock-out (UVLO)  with ready (RDY) pin indication
  • Active output pull-down and default low outputs with low supply or floating inputs
  • 3 V to 5.5 V input supply voltage
  • 15 V to 30 V output driver supply voltage
  • CMOS compatible inputs
