IR unveils accurate current-sensing devices for automotive applications
International Rectifier
AUIR331x
International Rectifier has launched the AUIR331x range of high-side intelligent power-switch (IPS) devices with accurate current-sensing and built-in protection circuits for automotive applications.
The IPS devices are claimed to enhance reliability in intelligent glow-plug controls, auxiliary positive temperature coefficient (PTC) heaters, engine-cooling fan drivers and interior fan controllers.
The current-sensing accuracy, particularly at low current, enables precise monitoring of load current in order to provide additional data to the microcontroller for diagnostic applications.
In many applications, additional protection devices such as fuses can be eliminated, according to the company.
The over-current shutdown protection feature is programmable, which allows optimisation according to the requirements of the load or the application.
Key specifications
- Includes all protection functions to ensure safe and reliable automotive application up to 30A continuous and 90A peak
- Devices integrate over-temperature and over-current shutdown
- Current-sensing function
- In the case of a reverse battery condition, an integrated protection circuit turns the main MOSFET switch on, helping to relieve the intrinsic body diode.
- Current-sensing function adds value to microprocessor-based systems and modules by improving diagnostic capabilities.
- Includes all protection functions to ensure safe and reliable automotive application up to 30A continuous and 90A peak
- ESD protection
- Active clamp circuit
- Subject to dynamic and static part average testing
- 100 per cent automated wafer-level visual inspection
- Qualified according to AEC-Q100 standards
- Feature an environmentally friendly, lead-free and RoHS-compliant bill of materials
