High-Side, Current-Sense Amplifiers with
12-Bit ADC and Op Amp/Comparator MAX9611/MAX9612
General Description
The MAX9611/MAX9612 are high-side current-sense
amplifiers with an integrated 12-bit ADC and a gain
block that can be configured either as an op amp or
comparator, making these devices ideal for a number of
industrial and automotive applications.
The high-side, current-sense amplifiers operate over a
wide 0V to 60V input common-mode voltage range. The
programmable full-scale voltage (440mV, 110mV, and
55mV) of these amplifiers offers wide dynamic range,
accurate current measurement, and application flexibility
in choosing sense resistor values. A choice of either an
internal op amp or a comparator is provided to the user.
The internal amplifier can be used to limit the inrush cur-
rent or to create a current source in a closed-loop sys-
tem. The comparator can be used to monitor fault events
for fast response.
An I2C controlled 12-bit, 500sps analog-to-digital con-
verter (ADC) can be used to read the voltage across the
sense resistor (VSENSE), the input common-mode voltage
(VRSCM), op-amp/comparator output (VOUT), op-amp/
comparator reference voltage (VSET), and internal die
temperature. The I2C bus is compatible with 1.8V and
3.3V logic, allowing modern microcontrollers to interface
to it.
The MAX9611 features a noninverting input-to-output
configuration while the MAX9612 features an inverting
input-to-output configuration.
The MAX9611/MAX9612 operate with a 2.7V to 5.5V
supply voltage range, are fully specified over the -40NC
to +125NC automotive temperature range, and are avail-
able in a 3mm x 5mm, 10-pin FMAXM package.
