2 / 15 page Data Sheet BTS550 Infineon Technologies AG 2 2010-June-01 Pin Symbol Function 1 OUT Output to the load. The pins 1 and 5 must be shorted with each other especially in high current applications!3) 2 IN Input, activates the power switch in case of short to ground 3 Vbb Positive power supply voltage, the tab is electrically connected to this pin. In high current applications the tab should be used for the Vbb connection instead of this pin4). 4 IS Diagnostic feedback providing a sense current proportional to the load current; zero current on failure (see Truth Table on page 7) 5 OUT Output to the load. The pins 1 and 5 must be shorted with each other especially in high current applications!3) Maximum Ratings at Tj = 25 °C unless otherwise specified Parameter Symbol Values Unit Supply voltage (see page 4 and 5) Vbb 40 V Supply voltage for short circuit protection, Tj,start =-40°C ...+150°C: (E AS limitation see diagram on page 10) Vbb 34 V Load current (short circuit current, see page 5) IL self-limited A Load dump protection VLoadDump = UA + Vs, UA = 13.5 V RI5) = 2 Ω, RL = 0.54 Ω, td = 200 ms, IN, IS = open or grounded VLoad dump6) 80 V Operating temperature range Storage temperature range Tj Tstg -40 ...+150 -55 ...+150 °C Power dissipation (DC), TC ≤ 25 °C Ptot 360 W Inductive load switch-off energy dissipation, single pulse Vbb = 12V, Tj,start = 150°C, TC = 150°C const., IL = 20 A, ZL = 15 mH, 0 Ω, see diagram on page 10 EAS 3J Electrostatic discharge capability (ESD) Human Body Model acc. MIL-STD883D, method 3015.7 and ESD assn. std. S5.1-1993, C = 100 pF, R = 1.5 k Ω VESD 4kV Current through input pin (DC) Current through current sense status pin (DC) see internal circuit diagrams on page 8 and 9 IIN IIS +15 , -250 +15 , -250 mA 3) Not shorting all outputs will considerably increase the on-state resistance, reduce the peak current capability and decrease the current sense accuracy 4) Otherwise add up to 0.5 m Ω (depending on used length of the pin) to the RON if the pin is used instead of the tab. 5) RI = internal resistance of the load dump test pulse generator. 6) VLoad dump is setup without the DUT connected to the generator per ISO 7637-1 and DIN 40839. |
