MicroPower Direct Presents IGD962-8A, Hybrid Integrated, Isolated N-Channel IGBT Driver

By MicroPower Direct | July 13, 2016

Now available from MicroPower Direct, the IGD962-8A is a hybrid integrated circuit specifically designed to provide the isolated gate drive required to control high-speed, high-power IGBT modules.

The IGD962-8A converts a TTL compatible input signal into a fully isolated +15V/-10V gate drive with a peak drive current of 8A. An internal, high-speed opto-coupler provides an isolated (3,750 VAC) control signal with a CMR ratio of 30 kV/µS for precise switching at high speed. A built-in “desaturation detector” provides short circuit protection. A fault signal is generated if the detector is activated. The timing of the fail signal is variable, allowing users to tailor the unit to specific application requirements.

The IGD962-8A uses a two-supply drive topology. One external DC/DC (also available from MPD) is used to set up the isolated +15V/-10V gate drive. A low cost POL may be used to provide the input signal voltage (+5 VDC).

The IGD962-8A is packaged in a compact SIP package to minimize board space required. It is specified for use over the operating temperature range of -40°C to +70°C.

Typical applications would include high-frequency welding systems, solar converters, uninterruptible power supplies (UPS) and automotive/appliance motor drives. The IGD962-8A is fully compatible with M57962AL type drivers.

Key Features

  • IGD962-8A converts a TTL compatible input signal into a fully isolated +15V/-10V gate drive with a peak drive current of 8A
  • Operating temperature range of -40°C to +70°C
  • Recommended for use with 600V Series IGBT (up to 600A), 1200V Series IGBT (up to 400A), and 1700V Series IGBT (up to 200A)
