Prolific Tech · USB Converters · SSOP-28

PL2586A2ZJG8P1 from Prolific Tech, in a SSOP-28. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VSS power_in Ground reference for the device.
2 XO output 12MHz crystal oscillator output.
3 XI input 12MHz crystal oscillator input.
4 DM4 bidirectional USB D- signal for the 4th downstream port.
5 DP4 bidirectional USB D+ signal for the 4th downstream port.
6 DM3 bidirectional USB D- signal for the 3rd downstream port.
7 DP3 bidirectional USB D+ signal for the 3rd downstream port.
8 DM2 bidirectional USB D- signal for the 2nd downstream port.
9 DP2 bidirectional USB D+ signal for the 2nd downstream port.
10 DM1 bidirectional USB D- signal for the 1st downstream port.
11 DP1 bidirectional USB D+ signal for the 1st downstream port.
12 VDDR12 power_out 1.2V output from the 3.3V to 1.2V LDO.
13 VDD33 power_in 3.3V input for the 3.3V to 1.2V LDO (operating range 3.0 V to 3.6 V per Section 9.2).
14 REXT input USB PHY bias reference pin.
15 DMU bidirectional USB D- signal for the upstream port (the datasheet text reads D-; see review_required).
16 DPU bidirectional USB signal for the upstream port, labelled D- in the pin table (see review_required; likely D+).
17 SRST input System reset pin, pulled up by default.
18 VBUS_IN input USB VBUS facing port used to monitor VBUS power state; the chip starts function when VBUS_IN = 1.
19 PSELF bidirectional Bus power monitor distinguishing self-powered (high) from bus-powered (low) operation, default pull-up; can support DCP mode with VBUS connected.
20 VDD5 power_in 5V input for the LDO (VBUS range 3.0 V to 5.5 V per Section 9.2).
21 VDDR33 power_out 3.3V output from the 5V LDO.
22 DRV bidirectional LED control and charging hub enable, default pull-down; tied to GND for hub active/suspend indication, pulled high to enable BC1.2 charging mode.
23 LED1/EESCL bidirectional LED control for downstream ports 1 and 3, and EEPROM clock (SCL), default pull-down.
24 LED2/GLEDEN bidirectional LED control for downstream ports 2 and 4, and group LED indicator enable when pulled high to 3.3V, default pull-down.
25 PWRJ bidirectional Power switch enable for the 4 downstream ports in ganged power mode, active low, default pull-up.
26 OVCJ bidirectional Global over-current detection indicator for the 4 downstream ports, active low, default pull-up.
27 TEST / EESDA bidirectional Test mode enable and EEPROM data pin, default pull-up, active low; leave as no-connect or connect to EEPROM SDA for normal use.
28 VDD12 power_in 1.2V power input (operating range 1.08 V to 1.32 V per Section 9.2).
