ZHCSK65E November 2006 – October 2019 TPS2410 , TPS2411
PRODUCTION DATA.
A resistor connected from this pin to GND sets the MOSFET fast turn-off comparator threshold. The threshold is slightly positive when the RSET pin is left open. Current drawn by the resistor programs the turn-off voltage to increasing negative values. The TPS2411 must have a negative threshold programmed to avoid an unstable condition at light load. The expression for R(RSET) in terms of the fast comparator-trip voltage, V(OFF), follows.
The units of the numerator are (V × V/A). V(OFF) is positive for V(A) greater than V(C), V(OFF) is less than 3 mV, and R(RSET) is in ohms.
