Toshiba Launches Small Single-Channel 3A High-Side Automotive IPD

Toshiba Corporation has launched the TPD1055FA, a single-channel high-side switch intelligent power device (IPD) that adopts a small-sized package for use in automotive applications. Mass production is scheduled to start at the end of this month. The product is fabricated with BiCD process, allowing introduction of a new WSON10 package line-up. This reduces the mounting area to approximately 30% that of equivalent products1 in a SOP-8 package, contributing to the downsizing of equipment. Automotive applications that use a 12V battery with a 3A or lower current, such as solenoid valve drives, mechanical relay drives, driving lamps, and load switches.

Key features of the TPD1055FA include: BiCD process (P-channel DMOS output@VDSS=40V); Supply voltage: VDD(opr)=5 to 18V; Built-in protection functions such as overcurrent, over-temperature; Build-in diagnostic functions include overcurrent, overtemperature, open load, short to VDD-output; Low Drain-Source ON-resistance; RDS(ON)=0.12Ω(max)@VDD=8 to 18V, Io=-2A, Tch=25°C; and a WSON10 (3mm x 3mm) package.
