Description
Input supply voltage pin. Bypass with a 220 m F capacitor to GND.
Not internally connected. For better heat flow, connect to GND (exposed pad).
V TT regulator output pin, which is preset to 50% of V DDQ .
Not internally connected. For better heat flow, connect to GND (exposed pad).
Ground pin (analog).
Ground pin (power).
This pin is for V DDQ output voltage adjustment. It is available as long as V DDQ is enabled.
During Manual/Thermal shutdown, it is tightened to GND. The V DDQ output voltage is set
using an external resistor divider connected to ADJSD:
V DDQ = 1.25 V × ((R1 + R2) / R2)
Where R1 is the upper resistor and R2 is the ground ? side resistor. In addition, the ADJSD pin functions as
a Shutdown pin. When ADJSD voltage is higher than 2.7 V (SHDN_H), the circuit is in Shutdown mode.
When ADJSD voltage is below 1.5 V (SHDN_L), both VDDQ and VTT are enabled. A low ? leakage Schottky
diode in series with ADJSD pin is recommended to avoid interference with the voltage adjustment setting.
V DDQ regulator output voltage pin.
The backside exposed pad which serves as the package heatsink. Must be connected to GND.
