Details:

SLMi33x series
40V, 1.5A-4A compatible optocoupler single channel isolated driver with protection function
The SLMi33x series is a single channel isolated driver with protection function compatible with optocouplers, which has active protection functions, including de saturation overcurrent detection, UVLO, fault detection, and Miller clamping. The peak output current of SLMi330/1 is 1.5A, SLMi332/3 is 2.5A, SLMi334/5 is 4.0A, and SLMi330/3/5 provides automatic fault reset function. The default de saturation voltage threshold for devices without suffix H is 6.5V, while for devices with suffix H, the default de saturation voltage threshold is 9V. The input side power supply voltage range is 3V to 18V, and the output side power supply voltage range is 14V to 40V. All power supply voltage pins have undervoltage lockout (UVLO) protection. Internal Desaturation (DESAT) fault detection can identify whether the IGBT is in an overcurrent state. When de saturation is activated, the fault signal is transmitted to the input side through an isolation barrier, pulling the FAIL output pin low and shielding the input signal. When powered by a bipolar power supply, when the IGBT is turned off normally, its gate voltage is clamped to VEE2. If the driving power supply is unipolar, an active Miller clamp can be used to allow Miller current to flow through a low impedance path, preventing the IGBT from being accidentally turned on.
The SLMi33x series adopts SOP16W packaging, providing 5kVRMS isolation withstand voltage in accordance with UL1577 standard, and has a minimum common mode transient immunity (CMTI) of 150kV/us.
