logic low, the ADP3209D shuts off. In shutdown mode, the
controller holds DRVH and DRVL low, shorts the capacitors
of the SS and PGDELAY pins to ground, and drives PWRGD
to low.
during startup and shutdown of the ADP3209D. 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.
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 1.15 V.
The user must adhere to proper power−supply sequencing
The ADP3209D has an output current monitor. The
