Product Summary

The MAX4172ESA is a low-cost, precision, high-side currentsense amplifier for portable PCs, telephones, and other systems where battery/DC power-line monitoring is critical. High-side power-line monitoring is especially useful in battery-powered systems, since it does not interfere with the ground path of battery charger.

Parametrics

MAX4172ESA maximum ratings: (1)V+, RS+, RS-, PG: -0.3V to +36V; (2)OUT: -0.3V to (V+ + 0.3V); (3)Differential Input Voltage, VRS+ - VRS-: ±700mV; (4)Current into Any Pin: ±50mA; (5)Continuous Power Dissipation (TA = +70℃) SO (derate 5.88mW/℃ above +70℃): 471mW; (6)μMAX (derate 4.10mW/℃ above +70℃): 330mW; (7)Operating Temperature Range: -40℃ to +85℃; (8)Storage Temperature Range: -65℃ to +150℃; (9)Lead Temperature (soldering, 10sec): +300℃.
