ELECTRICAL CHARACTERISTICS (continued)
(V
Typical values are at T
Low-Cost, Micropower, High-Side Current-Sense
Amplifier + Comparator + Reference ICs
Note 1: All devices are 100% production tested at T
Note 2: Guaranteed by PSR test.
Note 3: Guaranteed by OUT Voltage Error test.
Note 4: Guaranteed by Gain Accuracy test. Output voltage is internally clamped not to exceed 12V.
Note 5: Total OUT Voltage Error and Full-Scale Accuracy are the sum of gain and offset voltage errors.
Note 6: Measured at I
Note 7: +6.25mV = 1/16 of +100mV full-scale voltage.
Note 8: The device will not experience phase reversal when overdriven.
Note 9: All comparator tests are done with V
Note 10: V
Note 11: V
