Application Circuitry 3.1 Single DC-Motor Drive In this sample application the IC can realize the driving of a DC-motor via an external power N-FET bridge. The high side N-FET driving is done with a bootstrap output stage. The current control of the motor is done via shunt measurement and the reverse polarity protection of the bridge must be realized with an external power FET connected to the ground line. Short circuits of the bridge will be detected from fast comparators and in this case the bridge will be switched off. Weak short circuits are monitored with an external temperature sensor. The actual position can be read with hall sensors, which are connected to the timer capture inputs. The hall sensors are switched off during standby mode via a switchable battery voltage output. Optional it is possible to connect an external serial EEPROM via a SPI interface, if it isn’t allowed to use the integrated EEPROM because of security reasons.

This external load transistor decreases also the internal power dissipation which makes it possible to use this IC also for higher ambient temperatures. VBAT VS RTG VDD5V V1V8 Figure 3 - Application for higher VCC loads and higher ambient temperatures 3.3 High Side Reverse Polarity Protection With this IC it is also possible to realise a high side reverse polarity protection for the bridge Power-FET with a normal power N-FET.

The following circuitry shows a sample how to implement this together with our MLX81100. The communication between MLX8100 and external CAN controller is done via the SPI interface of the MelexCM. A bus wake-up will be signalised at the INH pin of the CAN transceiver. This signal will be used from a normal HV-IO pin to wake-up the MLX81100.

The high side N-FET driving is done with a bootstrap output stage. The current control of the motor is done via shunt measurement and the reverse polarity protection of the bridge must be realized with an external power FET connected to the ground line. Short circuits of the bridge will be detected from fast comparators and in this case the bridge will be switched off. Weak short circuits are monitored with an external temperature sensor. The actual position can be read with hall sensors, which are connected to the timer capture inputs. The hall sensors are switched off during standby mode via a switchable battery voltage output. If it is necessary to synchronize the motor movement via longer distances it can be done via the UART interface connected to an external high speed can transceiver. Via this interface together with a proprietary protocol it is possible that both motor-driver exchange real-time position information. Optional it is possible to connect an external serial EEPROM via a SPI interface, if it isn’t allowed to use the integrated EEPROM because of security reasons.

The high side N-FET driving is done with a bootstrap output stage. The current control of the motor is done via shunt measurement and the reverse polarity protection of the bridge must be realized with an external power FET connected to the ground line. Short circuits of the bridge will be detected from fast comparators and in this case the bridge will be switched off. Weak short circuits are monitored with an external temperature sensor. The reading of the direction and positions of a rotating encoder can be easy done via the timer capture inputs. With SW0 to SW5 and IO0 to IO3 it is possible to implement a switch matrix or to connect single switches.

The high side N-FET driving is done with a bootstrap output stage. The current control of the high side FETs will be done via shunt measurement and the shunt voltage is amplified with a differential amplifier connected to the ADC. The reverse polarity protection of the low side FETs is implemented with an external power FET connected to the ground line. Short circuits of the single FETs will be detected from fast comparators and in this case the FETs will be switched off. Weak short circuits are monitored with an external temperature sensor.
