FIGURE 1. ERROR Output Timing
*When
V
IN
1.3V the error flag pin becomes a high impedance,
and the error flag voltage rises to its pull-up voltage. Using V
out
as the pull-up voltage (see Figure 2), rather than an external 5V
source, will keep the error flag voltage under 1.2V (typ.) in this
condition. The user may wish to drive down the error flag
voltage using equal value resistors (10 k
suggested), to ensure
a low-level logic signal during any fault condition, while still
allowing a valid high logic level during normal operation.
