The new product, "TPD1058FA", is fabricated with a BiCD process, allowing introduction of a small-size WSON10 package (3mm x 3mm) line-up. This reduces the mounting area by approximately 70% that of Toshiba existing products in a SOP-8 package[1], contributing to the downsizing of equipment.

Key Features:

  • BiCD process(N-channel DMOS output@VDSS=60V)
  • Supply voltage: VDD(opr)=4.5 to 5.5V
  • Built-in protection and diagnostic functions:
    Protection functions: overcurrent, overtemperature, overvoltage
    Diagnostic functions: overcurrent, overtemperature, open load
  • Low Drain-Source ON-resistance:
    RDS(ON)=0.1Ω(max)@VDD=4.5 to 5.5V, Io=2A, Tch=25°C
  • Small package: WSON10 (3mm x 3mm)

Automotive applications that use a 12V battery with a 6A or lower current, such as solenoid valve drives, mechanical relay drives, driving lamps, and load switches
