A
/DIAG
A
Status of high-side and low-side switches A; open drain output.
This pin must be connected to an external pull-up resistor. When
externally pulled low, it disables half-bridge A. In case of fault
detection (thermal shutdown of a high-side FET or excessive
ON-state voltage drop across a low-side FET), this pin is pulled
low by the device (see Table 12: Truth table in fault conditions
(detected on OUTA))
6CS_DIS
Active high CMOS compatible pin to disable the current sense
pin
4IN
A
Clockwise input. CMOS compatible
7 PWM PWM input. CMOS compatible.
8CS
Output of current sense. This output delivers a current
proportional to the motor current, if CS_DIS is low or left open.
The information can be read back as an analog voltage across
an external resistor.
