XPD738BP

Shenzhen Fuman · USB Converters · TSSOP-16

XPD738BP from Shenzhen Fuman, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	VPWR	power_in	Input supply (VPWR). Operating range 3.6 V to 21 V; absolute max 28 V. Requires 4.7-10 uF CVPWR decoupling. Pins 1 and 2 are tied together.
2	VPWR	power_in	Input supply (VPWR), second pin tied to pin 1. UVLO rising 3.3 V / falling 2.9 V.
3	OPTO	output	Optocoupler driver output used to regulate the upstream AC-DC/DC-DC converter (line-loss compensation and dynamic VBUS regulation).
4	VFB	input	Voltage regulation feedback input; connects to the system VBUS feedback divider (RFB1=100 kOhm, RFB2=33 kOhm typ.) for Sink/Source current-source based VBUS trimming.
5	GND	power_in	Device ground / power return.
6	ISP2	input	Type-A port current-sense input. Senses across the external Rs (10 mOhm typical) for OCP and small-current (10 mA) shutdown detection on the Type-A port.
7	GD2	output	Gate-drive output for the external Type-A path PMOS switch that gates VBUSA to the USB Type-A receptacle.
8	VBUSA	power_out	Type-A port output supply node (source side of the external Type-A PMOS switched by GD2).
9	DP2	bidirectional	Type-A port D+ data line. Supports QC3.0+/3.0/2.0, FCP/SCP/HVSCP, AFC, BC1.2 DCP and Apple 2.4A handshake detection.
10	DM2	bidirectional	Type-A port D- data line. Used with DP2 for fast-charge protocol handshaking on the Type-A port.
11	DP1	bidirectional	Type-C port D+ data line.
12	DM1	bidirectional	Type-C port D- data line.
13	CC1	bidirectional	Type-C configuration channel 1. Handles DFP (Source) attach/orientation detection and BMC-encoded PD 2.0/3.0 communication. Rp broadcast current 180/330 uA (1.5A/3A modes).
14	CC2	bidirectional	Type-C configuration channel 2. Same function as CC1 for the flipped cable orientation.
15	VBUS	power_out	Type-C port VBUS output through the integrated 10 mOhm power switch. Pins 15 and 16 are tied together; recommended CVBUS 1 uF.
16	VBUS	power_out	Type-C port VBUS output, tied to pin 15. OVP/UVP monitored (+20% fast OVP, +15% slow OVP, -22% UVP relative to target).
