MAX4373/MAX4374/MAX4375 Low-Cost, Micropower, High-Side Current-Sense Amplifier + Comparator + Reference ICs
Electrical Characteristics (continued)
(VCC = +2.7V to +28V, VRS+ = 0 to +28V, VSENSE = 0V, V RESET = 0V, RLOAD= 1MΩ, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)
PARAMETER SYMBOL CONDITIONS MIN TYP MAX UNITS
Output High Leakage Current VCC = 28V, VPULL-UP = 5V (Note 10) 1 µA RESET Input High Voltage V 2.0 V IH RESET Input Low Voltage V 0.8 V IL Logic Input Current IIL, IIH VIL = 0, VIH = 5.5V, VCC = 28V -0.5 0.5 µA Minimum RESET Pulse Width t 1.5 µs RPW RESET Propagation Delay t 3 µs RPD
Note 1:
All devices are 100% production tested at TA = +25°C. All temperature limits are guaranteed by design.
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 IOUT = -500µA (RLOAD = 4kΩ for gain of +20V/V, RLOAD = 10kΩ for gain of +50V/V, RLOAD = 20kΩ for gain of +100V/V).
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 VRS+ = +12V.
Note 10:
VPULL-UP is defined as an externally applied voltage through a resistor to pull up the comparator output.
Note 11:
VOS is extrapolated from the gain accuracy test.
Typical Operating Characteristics
(VRS+ = +12V, VCC = +12V, RLOAD = 1MΩ, VRESET = 0V, VSENSE = 100mV, VPULL-UP = +5V, RPULL-UP = 10kΩ, TA = +25°C, unless otherwise noted.)
