Renesas intelligent power device range

Fourteen intelligent power devices (IPDs), including the μPD166023, designed for motor vehicle applications driving exterior lamps such as headlamps and fog lamps as well as seat heaters and motors are now available.

An IPD is a power IC that incorporates in a single package, or on a single chip, a power semiconductor switch (power MOSFETs) and its control circuit featuring interface to microcontroller as well as protection functions and self-diagnostic.

The devices are designed to detect and deal with error states instantly in order to provide a high level of durability.

The device line-up includes versions with on-resistance specification of 6, 8, 10, 12, 16, 25, 30, 50 and 90 mΩ.

The 6, 8, 10 and 12 mΩ versions are available in a seven-pin, TO252 package. This configuration allows direct control of the IPD from the MCU of the control unit.

Four devices are available with a 7-pin TO252 package, six products with a 12-pin high-heat-dispersion HSSOP package, and four with a 24-pin high-heat-dispersion HSSOP package.

They use the same signal lines to notify the control unit MCU when an error occurs. When changing to a device with a different on-resistance, the necessary changes to the software or to the printed wiring board are minimised.

The IPDs deliver good short durability. Power limitation protection enables faster detection of an overheating condition.
