Analog Devices Inc. USB-5PSMBUS-CABLEZ

Overview

USB-5PSMBUS-CABLEZ from Analog Devices is a USB-to-I²C interface dongle designed for programming and communication with the ADM1175/ADM1176/ADM1177/ADM1178 hot-swap controllers and ADM1191x power monitoring devices. It provides SCL, SDA, GND, CONV, and ALERT signals via a 5-pin crimp housing, connects standard PC USB ports to evaluation or system board headers, and requires external power supply for target device operation.

For engineers reviewing the USB-5PSMBUS-CABLEZ datasheet, USB-5PSMBUS-CABLEZ pinout, USB-5PSMBUS-CABLEZ application, or USB-5PSMBUS-CABLEZ equivalent, this page delivers verified interface signal mapping, supported device families, software version requirements (ADM1175–ADM1178/ADM119x eval software v3.0.0+), physical connector configuration, and evaluation-board-specific usage constraints.

Technical Context

The USB-5PSMBUS-CABLEZ implements a bidirectional I²C bus bridge using the Cypress CY7C68013A-56LFXC USB microcontroller, ADG836 analog switch, P82B96 I²C buffer, and ADP3303-3.3 LDO. It operates at 24 MHz clock frequency and supports standard-mode (100 kbps) and fast-mode (400 kbps) I²C signaling.

Signal conditioning includes active pull-up on SCL/SDA via P82B96, level translation between USB 3.3 V logic and target I²C voltage domains, and isolated CONV/ALERT lines routed directly from the CY7C68013A GPIOs to the 5-pin header - enabling hardware-triggered event monitoring during hot-swap or power-rail commissioning.

FAQ

What is the primary function of the USB-5PSMBUS-CABLEZ?

The USB-5PSMBUS-CABLEZ serves as a USB-to-I²C interface dongle that enables PC-based communication with Analog Devices' ADM1175–ADM1178 hot-swap controllers and ADM1191x power monitors. It routes SCL, SDA, GND, CONV, and ALERT signals between the host PC and target evaluation board, allowing register read/write, configuration, and real-time event monitoring via official evaluation software. The USB-5PSMBUS-CABLEZ does not provide power to the target device.

Which evaluation software versions support the USB-5PSMBUS-CABLEZ?

The USB-5PSMBUS-CABLEZ requires Version 3.0.0 or later of the ADM1175/ADM1176/ADM1177/ADM1178 and ADM119x evaluation software. Earlier versions lack driver compatibility and signal-handling logic for the CONV and ALERT lines. This requirement is explicitly documented in the Rev. 0 datasheet and confirmed by Analog Devices' software release notes for the ADM117x/ADM119x toolset.

Does the USB-5PSMBUS-CABLEZ supply power to the target board?

No, the USB-5PSMBUS-CABLEZ does not supply power to the target board. It draws 5 V from the host USB port solely for its internal circuitry (CY7C68013A, ADP3303, etc.). The connected ADM117x or ADM119x device must be powered separately through its designated supply rails. The USB-5PSMBUS-CABLEZ only transmits digital control and status signals: SCL, SDA, GND, CONV, and ALERT.

How is pin orientation verified on the USB-5PSMBUS-CABLEZ crimp housing?

Pin 1 on the USB-5PSMBUS-CABLEZ crimp housing is marked with a triangle symbol, as shown in Figure 1 of the official datasheet. Users must align this triangle with Pin 1 on the target 5-pin header (typically marked by square pad, silk-screen "1", or notch) to ensure correct SCL/SDA/GND/CONV/ALERT routing. Reversal risks communication failure or potential damage to the dongle or target IC.

Can the USB-5PSMBUS-CABLEZ be used with ADM1062–ADM1069 super sequencers?

No, the USB-5PSMBUS-CABLEZ is not compatible with the ADM1062–ADM1069 family. That device group requires the 3-pin USB-SMBUS-CABLEZ variant, which lacks CONV and ALERT lines and uses different signal routing and software drivers. Attempting to use the USB-5PSMBUS-CABLEZ with ADM1062–ADM1069 evaluation boards will result in unrecognized hardware or communication timeout errors in the evaluation software.
