Description
The STGAP1AS is a galvanically isolated single
gate driver for N-channel MOSFETs and IGBTs
with advanced protection, configuration and
diagnostic features. The architecture of the
STGAP1AS 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 rail-to-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.
