Functional description

The STSPIN230 device is a protected triple half-bridge motor driver.

6.1

Standby and power-up

The device provides a low consumption mode which is set forcing the STBY\RESET input

When the device is in standby status the power stage is disabled (outputs are in high

impedance) and the supply to the integrated control circuitry is cut off. When the device

leaves the standby status, all the control circuitry is reset to power-up condition.

6.2

Motor driving

The outputs of the three half-bridges are directly driven through the logic inputs as listed in

Table 8.
