FUNCTION
Detailed Description
The MAX4373 high-side current-sense supervisor fea-
tures a high-side current-sense amplifier, bandgap ref-
erence, and comparator with latching output to monitor
a supply for an overcurrent condition (Figure 1). The
latching output allows the comparator to shut down a
power supply without oscillations. The MAX4374/
MAX4375 offer an additional comparator to allow win-
dow detection of the current.
Current-Sense Amplifier
The internal current-sense amplifier features a 0V to
+28V input common-mode range that is independent of
the supply voltage. With this feature, the device can
monitor the output current of a battery in deep dis-
charge and also high-side current-sensing voltages
exceeding VCC.
The current-sense amplifier is also suitable for low-side
current sensing. However, the total output voltage error
will increase when VRS+ falls below 2V, as shown in
the
Electrical Characteristics and Typical Operating
Characteristics.

MAX4374/MAX4375
Voltage Output. VOUT is proportional to VSENSE (VRS+ - VRS-).
MAX4373
Comparator Input 1. Positive input of an internal comparator. The nega-
tive terminal is connected to a 0.6V internal reference.
Comparator Input 2. Terminal of a second internal comparator. The pos-
itive terminal for the MAX4374 and the negative terminal for the
MAX4375. The other terminal is connected to a 0.6V internal reference.
Open-Drain Comparator Output. Output of the second unlatched inter-
nal comparator.
Open-Drain Comparator Output. Latching output of the comparator con-
trolled by CIN1. Connect RESET to GND to disable the latch.
Reset Input. Resets the output latch of the comparator at CIN1.
