Evaluation board for 1ED3491Mx12M - 1200 V, 9 A, single-channel flexible isolated gate driver with active Miller clamp, adjustable DESAT and Soft-off
The EVAL-1ED3491MX12M is in half-bridge configuration with two gate driver ICs (1ED3491MU12M) to drive power switches such as Si MOSFETs, IGBTs and SiC MOSFETs. The switch type can be freely chosen. The board has a size of 85 x 55 x 15 mm without any power switch assembled. TRENCHSTOP™ IGBT IKW40N120H3 or CoolSiC™ MOSFET IMW120R030M1H is recommended. This board is best suited for double pulse testing and evaluation. The low voltage supply interface can be controlled by a pulse generator, a microcontroller or any other suitable digital circuit. The evaluation board has a power supply for the primary and secondary sides implemented.
Summary of Features
- Galvanically isolated power supply for both secondary sides
- Resistors marking for the adjustable functions of each gate drive
- Flexible EiceDRIVER™ Enhanced single channel isolated gate driver 1ED34xx family (X3 analog family)
- ±9 A typical sinking and sourcing peak output current
- 40 V absolute maximum output supply voltage
- Separate source and sink outputs
- Active Miller clamp (clamp driver for external MOSFET)
- Precise VCEsat detection (DESAT) with fault output
- IGBT soft turn-off after desaturation detection
- Parameter adjustment from input side with external resistor:
- Adjustable DESAT filter time with ADJB pin
- Adjustable soft-off current level with ADJA pin
- FLT and RDY status signaling to µController
- 11 V/12 V undervoltage lockout (UVLO) protection with hysteresis
Benefits
- Over-temperature shut down at 160 °C (±10 °C)
- Tight IC-to-IC propagation delay matching (30 ns max.)
- High common-mode transient immunity CMTI >200 kV/μs
- Suitable for operation at high ambient temperature up to 125 °C
- Small space-saving DSO-16 fine pitch wide-body package with large creepage distance (>8 mm)
- UL 1577 (planned) VISO = 6 kV (rms) for 1 s, 5 kV (rms) for 1 min
- Enable fast design cycles due to low external component count and still offers adjustable DESAT with Soft-off functionality
- The precise threshold and timings, combined with UL 1577 certification enable superior application safety
- Perfect fit for all applications requiring a reliable DESAT protection, benefit from an active Miller clamp and prefer small PCB space requirements
- Fast EV charging
- Motor control and drives
- Solutions for solar energy systems
- Uninterruptible Power Supply (UPS)
