5 Pin Configuration and Functions

GUID-20220602-SS0I-ZSGV-MXZR-4SLJ6NGGVKGS-low.png Figure 5-1 DAP Package, 32-Pin HTSSOP (Top View)
Pin Functions
PIN I/O(1) DESCRIPTION
NAME NO.
VTTREF 4 O Reference output. Connect to GND through 0.1-µF ceramic capacitor.
VDDQSNS 5 I VDDQ sense input. Reference input for VTTREF.(2)
VLDOIN 7 I Supply voltage for the LDO. Connect to VDDQ voltage or an alternate voltage source.
8
PGND 9 — Power ground. Connect to system ground.
10
11
EN 20 I Enable pin. Driving this pin to logic high enables the device; driving this pin to logic low disables the device.
VDD 21 I 2.5- or 3.3-V power supply. A ceramic decoupling capacitor with a value between 1 and 10 µF is required.
PGOOD 22 O PGOOD output pin. PGOOD pin is an open drain output to indicate the output voltage is within specification.
VTT 23 O Power output for VTT LDO.
24
25
26
AGND 28 — Signal ground. Connect to system ground.
VTTSNS 29 I Voltage sense for VTT. Place capacitor close to pin. Route sense line to VTT near load.
NC 1-3, 6, 12-19, 27, 30-32 — No connect. These pins are not internally connected. It is recommended to connect these pins to ground to prevent charge buildup; however, these pins can also be left open or tied to any voltage between ground and VDD.
Thermal Pad — Connect to PGND. This is internally floating.
(1) I = Input, O = Output, — = Other
(2) VDDQSNS shall be connected to the regulated voltage supplying VDDQ. If the VDDQ supply is also used for VLDOIN, an RC filter is recommended to isolate transients from VLDOIN to VDDQ.
