S6J3310/20/30/40 Series
Pulse condition specification:
U_pulse = max -40 V
T_pulse = max 1 ms
#_pulse = max 5000
Current and Power Dissipation
U_peak = -40 V
R_serial = 22 k
=> I_pin = 1.8 mA
U_out = -0.1 V (current drawn mainly over NMOS transistor)
=> I_total = 50 pins x 1.8 mA = 90 mA
=> P_total = 50 pins x (1.8 mA x 0.1 V) = 9 mW
I_total and P_total are within allowed limits of extended specification.
• The - B signal should always be applied by connecting a limiting resistor between the - B signal and the microcontroller.
• The value of the limiting resistor should be set so that the current input to the microcontroller pin does not exceed rated
values at any time regardless of instantaneously or constantly when the - B signal is input.
• Do not leave - B input pins open.
Example of a recommended circuit
WARNING:
−
Semiconductor devices may be permanently damaged by application of stress (including, without limitation, voltage, current
or temperature) in excess of absolute maximum ratings. Do not exceed any of these ratings.
*C Relevant pins: All general-purpose ports and analog input pins
• Corresponding pins: all general-purpose ports
• Use within non operation conditions. The device is not supplied (VCC5: off, VCC12: off, VCC53: off).
• Use at DC voltage (current).
MCU is non-operational, PCB is in reverse polarity condition (supply of the MCU is off), negative biased voltage level (-B
signal) is applied to inactive IO according to following specification (must not be exceeded).
