Channel 2 Current-Sense-Resistor Connection. Connect to the external supply powering channel 2’s
MESFET drain, in the range of +0.5V to +11V (MAX11014) or +5V to +32V (MAX11015). Bypass with
a 1µF and a 0.1µF capacitor in parallel to AGND. If unused, connect to RCS1+.
Channel 2 Current-Sense-Resistor Connection. Connect to the channel 2 MESFET drain. Decouple as
required by the application. If unused, connect to RCS2+.
Channel 1 Current-Sense-Resistor Connection. Connect to the channel 1 MESFET drain. Decouple as
required by the application. If unused, connect to RCS1+.
Channel 1 Current-Sense-Resistor Connection. Connect to the external supply powering channel 1’s
MESFET drain, in the range of +0.5V to +11V (MAX11014) or +5V to +32V (MAX11015). Bypass with
a 1µF and a 0.1µF capacitor in parallel to AGND. If unused, connect to RCS2+.
Operating Safe Channel 1 Input. Set OPSAFE1 high to clamp GATE1 to ACLAMP1 for fast protection
of enhancement FET power transistors.
Operating Safe Channel 2 Input. Set OPSAFE2 high to clamp GATE2 to ACLAMP2 for fast protection
of enhancement FET power transistors.
BUSY Output. BUSY asserts high under certain conditions when the device is busy. See the BUSY
Output section.

ALARM Output. ALARM asserts when the temperature or voltage measurements exceed their preset
high or low thresholds.
