SLDS269A March 2022 – May 2022 LP5891
PRODUCTION DATA
The IREF resistor short protection (ISP) function prevents unwanted large currents from flowing through the constant-current output when the IREF resistor is shorted accidently. The LP5891 device turns off all output channels when the IREF pin voltage is lower than 0.19 V (typical). When the IREF pin voltage goes higher than 0.325 V (typical), the LP5891 device resumes normal operation.
