• Manufacturer: Motorola

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.
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.

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
requirements of the half-bridge driver outputs and high-side
output driver, multiple VSUP terminals are provided.
