Although the TPSi1085 has reverse polarity protection, please ensure that the polarities are correct in order to avoid
damaging the input power supply. Supply must be correctly fused.
INPuT POWER (CN3)
CN3 is the input power connector. The input range is +9V to +33V DC. For enhanced protection, the
TPSi1085 provides active input clamping, transient suppressors, current limiting, and reverse polarity
protection. See the Protection Features section for more information. The quick-disconnect screw
terminal block is intended for 28 to 16 AWG wires.

POWER SuPPLY STATuS (CN1-10)
The Power Supply Status (PS-STAT) output sends an active low signal when the input voltage is
outside of the range, +9V to +33V DC, and when the outputs are turned off. Once the input voltage
returns within the range and the power outputs turn on, the PS-STAT signal will turn off. The quick-
disconnect screw terminal block is intended for 28 to 16 AWG wires.
