International Rectiifer's IPS10xx family of low-side intelligent power switches (IPS), suited to automotive environments and similar harsh applications, include a logic-level input and diagnostic information pin to monitor/detect faults during operation. The output from this pin can be fed back to a microcontroller to trigger a specific sequence or restart strategy following a fault condition.

The IPS line features the IPS1011R, a 13m? device in a D-Pak that the company says allows designers to pack more current-handling capability into existing board layouts.

"Older technology IPS devices required larger packages for performance equivalent to these new devices," said Anthony Murray, automotive product manager. "Previous 13m? devices on the market required packaging in the larger D?PAK, a size difference of about 40 percent. In addition, additional diagnostic feedback is provided through the input pin. The new products include the IPS1021 (RDS is 25 m?) and the IPS1031 (RDS = 50 m?).

The new low-side family features all the standard protection features generally found in protected switches: Over-current, over-temperature, ESD protection and active clamp. These devices can also be used as replacements for mechanical relays. In some applications, the designer can apply these device to eliminate additional fuses or circuit breakers.

Prices are subject to change.
