MAX9928, MAX9929 输入范围、微功耗、单/双向
max9928, max9929 -0.1v至+28v输入范围、微功耗、单/双向电流检测放大器
the max9928/max9929 low-cost, uni-/bidirectional, high-side, current-sense amplifiers are ideal for monitoring battery charge and discharge currents in notebooks, cell phones, and other portable equipment. these devices feature 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 max9928f/max9928t feature a current output with transconductance ratios of 5µa/mv and 2µa/mv, respectively. an external resistor converts the output current to a voltage, allowing adjustable gain so that the input sense voltage can be matched to the maximum adc input swing. the max9929f/max9929t have a voltage output and integrate a 10kω output resistor for fixed voltage gains of 50v/v and 20v/v, respectively.
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.
the max9928/max9929 are fully specified over the -40°c to +125°c automotive temperature range, and available in 6-bump ucsp™ (1mm x 1.5mm) and 8-pin µmax® packages. the ucsp package is bump-to-bump compatible with the max4372_ebt.
