MAX976ESA

The MAX976ESA is designed as one kind of digitally controlled fuel-gauge interface that belongs to the MAX976 family. This device can be used in (1)smart-battery packs ; (2)battery-pack fuel gauging; (3)battery-pack overcurrent protection ; (4)digital current-sense instrumentation. Also this device operates with battery voltages from +4V to +28V and provides two micropower shutdown modes.

Features of the MAX976ESA are:(1)1% Accuracy over a 600A to 4A Current Range; (2)(RSENSE = 30m; (3)5V Input Offset Voltage (28V max); (4)SMBus 2-Wire (plus optional interrupt) Serial Interface; (5)2.00V Precision System Reference Output; (6)3.3V Linear-Regulator Output Powers External Circuitry; (7)Two Micropower Shutdown Modes; (8)Independent 32-Bit Charge and Discharge Coulomb Counters; (9)Battery-Overcharge/Overdischarge Protection; (10)Battery Short-Circuit/Overcurrent Protection; (11)On-Board Power MOSFET Drivers; (12)80A Quiescent Current; (13)<1A Shutdown Current; (14)Small 16-Pin QSOP Package; (15)(same board area as 8-pin SO).

The absolute maximum ratings of the MAX976ESA can be summarized as:(1)BATT, ODO, OCO, SHDN to GND:-0.3V to +30V;(2)SCL, SDA, INT, RST to GND:-0.3V to +6V;(3)REF, ODI, OCI to GND:-0.3V to (VL + 0.3V);(4)VL to GND:-0.3V to +6V;(5)CS to GND:-2V to +6V;(6)AGND to GND:-1V to +1V;(7)Lead Temperature (soldering, 10sec):+300°C;(8)Storage Temperature Range:-65°C to +165°C;(9)Operating Temperature Range:-40°C to +85°C.
