L6460 is intended to maximize the use of its components, so when an internal circuit is not
used it could be employed for other applications. Bridge 3, for example, can be used as a full
bridge or to implement two switching regulators with synchronous rectification: to obtain this
flexibility L6460 includes 2 separate regulation loops for these regulators; when the bridge is
used as a motor driver, the 2 regulation loops can be redirected on general purpose I/Os to
leave the possibility to assembly a switching regulator by only adding an external FET.
voltages. This regulator can be used to drive an external bipolar pass transistor to
generate high current/low ripple output voltages.
One bidirectional serial interface with address detection so that different ICs can share
the same data bus.
Integrated power sequencing and supervisory functions with fault signaling through
serial interface and external reset pin.
Fourteen general purpose I/Os that can be used to drive/read internal/external
analog/logic signals.
One 8-bit/9-bit A/D converter (100 kS/s @ 9-bit, 200 kS/s @8-bit). It can be used to
measure most of the internal signals, of the input pins and a voltage proportional to IC
temperature.
