APD3212/NCP3218/NCP3218G shuts off. In shutdown
mode, the controller holds the PWM outputs low, shorts the
capacitors of the SS and PGDELAY pins to ground, and
drives the DRVH and DRVL outputs low.
during startup and shutdown of the APD3212/NCP3218/
NCP3218G. All input pins must be at ground prior to
removing or applying VCC, and all output pins should be
left in high impedance state while VCC is off.
Thermal Throttling Control
monitoring circuit to detect whether the temperature of the
VR has exceeded a user−defined thermal throttling
threshold. The thermal monitoring circuit requires an
external resistor divider connected between the VCC pin
and GND. The divider consists of an NTC thermistor and a
resistor. To generate a 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−6.5 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.
Output Current Monitor
current monitor. The 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
to prevent it from going above 1.15 V.
