Note that a “+”,
“#”, or “-” in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing
pertains to the package regardless of RoHS status.
Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board.

FUNCTION
Reset Output. Reset asserts when V
CC
drops below factory set threshold or when MR receives
either an edge-triggered or level-triggered signal. For the open-drain version, the MAX16140,
connect a pullup resistor for active-low option and a pulldown resistor for active-high option.
Positive Supply Input Voltage. Connect V
CC
to the positive side of the input voltage. Bypass V
