Renesas releases automotive IPDs

Renesas Electronics Corporation has unveiled three new intelligent power devices (IPDs) for use in automotive turn signals and brake light applications.

The IPDs〞the?PD166011,?PD166013 and?PD166014〞integrate power metal-oxide-semiconductor field-effect transistors (power MOSFETs) into a single package as switching elements and control circuits for protection and self-diagnostic functions.

The devices include the?PD166011 with a 12-pin power HSSOP package and two output channels with an on-state resistance of 25m次〞the resistance at which a MOSFET operates in the on-state. A lower on-resistance translates into less loss and the ability to handle large current flows.

The other IPDs are the?PD166013, which has a 12-pin power HSSOP package and two output channels with an on-state resistance of 60m次, and the?PD166014 with a 24-pin power HSSOP package and four output channels with an on-state resistance of 60m次.

The products provide either two- or four-output channels in a single package and are offered in three different product versions, with different packages, on-state resistance, and output channel-count characteristics to meet a variety of customer requirements.

Each device can be used in combination with the company's existing?PD166009 or?PD166010 devices to drive exterior automotive lamps with varying characteristics, including turn signals, brake lights, headlights, cornering lamps and fog lamps.

A key feature of the IPDs is the provision of multiple output channels in a single package that make for more compact control units. They were fabricated with a new process that provides tolerance for high voltages and large currents and enables a single-chip configuration.

Compared to existing Renesas Electronics products with a single output channel and a TO-252 package, the?PD166011 and?PD166013 devices implement two output channels in a 12-pin power HSSOP package of about the same size. This means that a lamp-drive circuit block can be built using only half as many of the new IPD products, contributing to a smaller mounting area and a more compact control unit overall.

The devices come with three product versions with different packages, on-state resistance, and output channel-count characteristics to meet a variety of customer requirements. Of the three IPDs, two versions use the12-pin power HSSOP package and provide two output channels with an on-resistance of 25 m次 or 60 m次.

If, for example, the lamp drive load conditions change while the control unit is in the development phase, it is possible to switch to an IPD product with a lower on-state resistance while maintaining the same package and pin compatibility. The change can be made without the need to modify the design of the printed wiring board.
