Description:

The M57959L is one member of the hybrid integrated circuit which designed for driving N-channel IGBT modules in any gate-amplifier application. This device operates as an isolation amplifier for these modules and provides the required electrical isolation between the input and output with an opto-coupler. This device can be used to drive IGBT modules for inverter or AC servo systems application.

Features of the M57959L are1)electrical isolation between input and output with opto-coupler (Viso=2500 Vrms for 1 minutes);(2)two supply driver topology;(3)built-in short circuit protection circuit (with a pin for fault out);(4)TTL compatible input interface.

The absolute maximum ratings of the M57959L can be summarized as1)supply voltage:18 or -15 V;(2)input voltage (applied between 13 pin to 14 pin):-1 to +7 V;(3)output voltage (when the output voltage is "H"):Vcc V;(4)isolation voltage:2500 Vrms;(5)case temperature:85℃;(6)operating temperature:-20℃ to +60℃;(7)storage temperature:-25℃ to +60℃;(8)fault output current"20 mA;(9)input voltage:50 V.
