voltage that is proportional to temperature, the midpoint of
the divider is connected to the TTSNS pin. An internal
comparator circuit compares the TTSNS voltage to half the
VCC threshold and outputs a logic level signal at the VRTT
output when the temperature trips the user−set alarm
threshold. The VRTT output is designed to drive an external
transistor that in turn provides the high current, open−drain
VRTT signal required by the IMVP−6+ specification. The
internal VRTT comparator has a hysteresis of approximately

100 mV to prevent high frequency oscillation of VRTT
when the temperature approaches the set alarm point.
Current Monitor Function
IMON pin sources a current proportional to the inductor
current. A resistor from IMON pin to FBRTN sets the gain.
A 0.1 mF is added in parallel with R
ripple. The IMON pin is clamped to prevent it from going
above 1.15V
