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.
