6.3.1 Reverse-Voltage Protection

The XTR117 low compliance voltage rating (minimum operating voltage) of 7.5 V permits the use of various voltage protection methods without compromising operating range. Figure 6-2 shows a diode bridge circuit that allows normal operation even when the voltage connection lines are reversed. The bridge causes a two-diode drop (approximately 1.4 V) loss in loop supply voltage. This voltage drop results in a compliance voltage of approximately 9 V—satisfactory for most applications. A diode can be inserted in series with the loop supply voltage and the V+ pin to protect against reverse output connection lines with only a 0.7-V loss in loop supply voltage.
