MAX9929FABT+T

The MAX9929FABT+T is a -0.1V to +28V input range, micropower, uni/bidirectional, current sense amplifier in 6 pin UCSP package. Ideal for monitoring battery charge and discharge currents in notebooks, cell phones and other portable equipment. This device features a wide -0.1V to +28V input common-mode voltage range, low 20μA supply current with VOS less than 0.4mV and a gain accuracy better than 1.0%. The input common mode range is independent of the supply voltage, ensuring that the current-sense information remains accurate even when the measurement rail is shorted to ground. The MAX9929F has a voltage output and integrates a 10Kohm output resistor for a fixed voltage gain of 50V/V. A digital SIGN output indicates direction of current flow, so the user can utilize the full ADC input range for measuring both charging and discharging currents.

• Supply voltage range is 2.5V to 5.5V
• Operating temperature range from -40°C to 125°C
• Pin compatible with the MAX4372 in UCSP package
