The driver core’s reinforced electrical isolation targets systems with a working voltage of 900V, which is typical for 1200V IGBT modules and complies with the PD2 and OV II requirements of IEC 60664-1 and IEC 61800-5-1. The 2SC0115TA0-12 gate-driver core supports modules up to 2400A and switching frequencies of up to 50kHz.
With a footprint of 53.2x31mm and a profile of just 13mm, the gate-driver core is the most compact industrial unit of its type available. The highly integrated SCALE-2+ chipset uses about 85% fewer components than competing products and includes short-circuit protection by Vce-sat monitoring and independent supply-voltage monitoring from both the primary and secondary side. The new gate-driver core includes Soft Shut Down protection for applications with low stray-inductance. For more demanding environments the 2SC0115TA0-12 supports full AAC to control the IGBT voltage overshoot during turn-off.
Each of the two output channels is electrically isolated from the primary side and the other secondary channel. An output current of ±15A and 1.2W drive power is available per channel with a gate voltage swing of +15V to -6V. The turn-on voltage is regulated to maintain a stable 15V regardless of the output power level.
Michael Hornkamp, Senior Director of Marketing, High-Power Products, Power Integrations, commented: “The 2SC0115TA0-12 gate-driver core is a suitable platform for 600V and 1200V IGBT modules in medium power applications such as general purpose drives, UPS, photovoltaic inverters and medical applications, especially those with challenging, fast-switching requirements.”
