This single-chip solution integrates features that improve performance and ensure long-life in harsh environments. It can be used for fast-switching drive and protection of power IGBT’s, Si and SiC MOSFETs. The driver incorporates Solantro’s onchip coreless transformer technology to enable 3.75 kVrms input to output isolated voltage and high transient immunity (>50 kV/µs) as required in industrial and automotive applications. The driver is suitable for motor control, switch mode power supply (SMPS), PFC, UPS, EV-OBC, industrial pumps, and traction inverter applications. Its short propagation delay and small timing-skew help achieve optimum performance at higher switching speeds when compared with other driver solutions available in the market. All logic pins are TTL compatible for easy interface to standard controllers and MCUs. The SA6880-S architecture includes several control features protecting the device in harsh industrial and automotive environments. These integrated features include over-current (desaturation) sensing with soft-shutdown protection, high-side undervoltage lockout, active Miller-Current clamping and fault reporting. The driver supports bipolar and unipolar supply voltage configurations. In a bipolar configuration, the driver is typically supplied with voltages of +18 V and -5 V. For unipolar configuration, the driver is typically supplied with a positive 18 V (max 32 V). To meet UL isolation, creepage and clearance requirements the SA6880-S is available in a standard SOIC-16W (wide-body) package. © 2019 Solantro® The mark “Solantro” is a registered trademark of Solantro Semiconductor Corp.

VNEG) Note: 1) IP input controls signal for the driver output while IN is set to low. The IGBT is turned on if IP is set to high and IN is set to low, otherwise is turned off. A minimum pulse width is required to suppress glitches while controlling the IGBT. An internal pull-down resistor ensures that the IGBT is kept in off-state if terminal IP is left unconnected. 2) IN input control signals for the driver output while IP is set to high. The IGBT is turned on if IN- is set to low, and is turned off if IN- is set to high, while IN is kept high. © 2019 Solantro® The mark “Solantro” is a registered trademark of Solantro Semiconductor Corp.
