Description

The STGAP1S gapDRIVE™ is a galvanically

isolated single gate driver for N-channel

MOSFETs and IGBTs with advanced protection,

configuration and diagnostic features. The

architecture of the STGAP1S isolates the channel

from the control and the low voltage interface

circuitry through true galvanic isolation.

The gate driver is characterized by 5 A capability,

making the device also suitable for high power

inverter applications such as motor drivers in

hybrid and electric vehicles and in industrial

drives. The output driver section provides a railto-rail output with the possibility to use a negative

gate driver supply.

The input to output propagation delay results

contained within 100 ns, providing high PWM

control accuracy.

Protection functions such as the Miller clamp,

desaturation detection, dedicated sense pin for

overcurrent detection, output 2-level turn-off, VCE

overvoltage protection, UVLO and OVLO are

included to easily design high reliability systems.

Open drain diagnostic outputs are present and

detailed device conditions can be monitored

through the SPI. Each function's parameter can

be programmed via the SPI, making the device

very flexible and allowing it to fit in a wide range of

applications. Separate sink and source outputs

provide high flexibility and bill of material

reduction for external components.
