The MAX49017 is a space-saving, dual comparator with built-in voltage reference and push-pull output. The device is AEC-Q100 qualified, which is ideal for automotive applications: car battery monitoring systems, infotainment head units, and ADAS modules. The MAX49017 is available in an 8-pin, 2mm x 2mm TDFN package with side-wettable flanks.

The device features a Beyond-the-Rails^TM input, offers a supply voltage range from 1.7V to 5.5V, and consumes only 1.35μA of supply current. The device also features internal filtering to provide high RF immunity, important in automotive systems.

The device has a built-in 1.252V reference that is factory trimmed to an initial accuracy of 1% and better than 2.5% over the entire temperature range. The reference output is stable for capacitive loads up to 100pF or above 0.1µF (with an unstable region from 100pF and 0.1µF).

The MAX49017 is fully specified over -40°C to +125°C automotive temperature range.

Product Details

The MAX49017 evaluation kit (EV kit) is a fully assembled and tested circuit board to evaluate MAX49017 dual comparator with internal voltage reference. The MAX49017 EVKIT comes with a MAX49017ATA/VY+ installed that operate off a V_CC supply between 1.7V and 5.5V, an internal reference voltage of 1.252V, and have a wide -0.2V to +5.7V input voltage (V_IN) range. This EV kit demonstrates the MAX49017ATA/VY+ in an 8-pin 2mm x 2mm TDFN package with side-wettable flanks.
