Toshiba » TPD1055FA

Toshiba has developed TPD1055FA, targeted at solenoid valve drivers used for the control of automobile automatic transmissions and other applications. The package is smaller than the SOP-8 package (footprint 5×6 mm) used in our conventional products such as TPD1038F and TPD1053F.

Toshiba - TPD1055FA package WSON10

Features

  • BiCD process (0.13 μm design rule, output P-ch DMOS drain-to-source breakdown voltage 40 V)
  • Operating supply voltage: VDD = 5 to 18 V
  • 3.3 V and 5 V compatible
  • Built-in protection functions: overcurrent (shorted load) and over temperature
  • Built-in diagnosis functions: overcurrent (shorted load), over temperature, open load, and short circuit between the output pin and power pin (short to VDD - output)
  • Low Drain-Source ON-resistance: RDS(ON) = 0.12 Ω (max) @VDD = 8 to 18 V, IO = –2 A, Tch = 25°C
  • Small and high heat-dissipation package: WSON10

Applications

  • Applications of 3 A or less, used with a 12 V power supply (e.g., automobile)
  • Major automobile applications: Solenoid valve driver, mechanical relay driver, lamp driver
