General Description
The MAX9937 is a tiny automotive grade current-sense
amplifier designed for unidirectional high-side current-
sense applications. This device addresses major areas
of concern for automotive applications including load-
dump protection up to +40V, reverse-battery protec-
tion, and filtering for EMI and transient performance.
The MAX9937 also features a low input offset voltage of
±1.2mV (max) at +25°C with a low temperature drift of
just 1V/°C (typ).
The MAX9937 is available in a 5-pin SC70 package and
is rated over the -40°C to +125°C temperature range.
