TLE 4275 V33
Block Description and Electrical Characteristics
Reset Output “RO”:
The Reset Output “RO” is an open collector output requiring an external pull-up resistor to a voltage rail V_IO. As
the maximum Reset Output Sink Current I_RO,max is limited, the minimum external pull-up resistor calculates:
R_{RO,external,min} = V_IO / I_RO,max.
