NOTES:
7. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established
by characterization and are not production tested.
8. DEFINITION OF TERMS:
• V_SENSEA = V_SENSE @ 100mV
• V_SENSEB = V_SENSE @ 20mV
• V_OUTA = V_OUT @ V_SENSEA = 100mV
• V_OUTB = V_OUT @ V_SENSEB = 20mV
