No Connection. Not internally connected.
SGND
SGND
Signal Ground
6
PGND
PGND
Ground. PGND is also the return path for the overvoltage protector pulldown current
for the MAX15009. In this case, connect PGND to SGND at the negative terminal of the
bypass capacitor connected to the source of the external MOSFET. For the
MAX15011, connect PGND to SGND together to the local ground plane.
7
RESET
RESET
Active-Low Open-Drain Reset Output.
RESET
is low while OUT_LDO is below the reset
threshold. Once OUT_LDO has exceeded the reset threshold,
RESET
remains low for
the duration of the reset timeout period then goes high.
9
CT
CT
Reset Timeout Adjust Input. Connect a capacitor (C
RESET
) from CT to ground to adjust
the reset timeout period. See the
Setting the
RESET
Timeout Period
section.
10
FB_PROT
Overvoltage-Threshold Adjustment Input. Connect FB_PROT to an external resistive
voltage-divider network to adjust the desired overvoltage threshold. Use FB_PROT to
monitor a system input or output voltage. See the
Setting the Overvoltage Threshold
(MAX15009 Only)
section.
12
GATE
Protector Gate Drive Output. Connect GATE to the gate of an external n-channel
MOSFET. GATE is the output of a charge pump with a 45μA pullup current to 8.1V
(typ) above IN during normal operation. GATE is quickly turned off through a 63mA
internal pulldown during an overvoltage condition. GATE then remains low until
FB_PROT has decreased below 96% of the overvoltage threshold. GATE pulls low
when EN_PROT is low.
13
SOURCE
Output-Voltage Sense Input. Connect SOURCE to the source of the external n-channel
MOSFET.
