CURRENT LIMITATION FREQUENCY INPUT
TERMINAL (FGEN)
high-side inrush current limiter PWM frequency. This input is
not a real PWM input terminal; it should just supply the period
of the PWM. The duty cycle will be generate automatically.
be in the range of 0.1 kHz to 20 kHz.
BACK ELECTROMAGNETIC FORCE OUTPUT
TERMINAL (BEMF)
electromagnetic force (BEMF). This feature is mainly used in
step motor applications for detecting a stalled motor. In order
to evaluate this signal the terminal must be directly connected
to terminal PTD0/TACH0/BEMF.
RESET TERMINAL (RST_A)
It is an open drain with pull-up resistor and must be
connected to the
INTERRUPT TERMINAL (IRQ_A)
indicating errors or wake-up events. It is an open drain with
pull-up resistor and must be connected to the
the MCU.
SLAVE SELECT TERMINAL (SS)
analog chip. All other SPI connections are done internally.
must be connected to PTB1 or any other logic I/O of the
microcontroller.
LIN BUS TERMINAL (LIN)
transmitter and receiver. It is suited for automotive bus
systems and is based on the LIN bus specification.
HALF-BRIDGE OUTPUT TERMINALS (HB1:HB4)
configured as four half-bridge driver outputs. The HB1:HB4
outputs may be configured for step motor drivers, DC motor
drivers, or as high-side and low-side switches.
overtemperature protected, and they feature current recopy,
current limitation, and BEMF generation. Current limitation
and recopy are done on the low-side MOSFETs.
POWER SUPPLY TERMINALS (VSUP1:VSUP3)
nominal input voltage is designed for operation from 12 V
systems. Owing to the low ON-resistance and current

The switch is protected against overtemperature and
overcurrent. The output is capable of limiting the inrush
current with an automatic PWM generation using the FGEN
module.
