Product details
Overview
The SLG55596V from Silego Technology is a USB host charger identification IC with integrated high-speed analog switches for D+/D− signal routing. It performs automatic USB Battery Charging Specification Rev 1.2 compliance detection (including data contact detection), supports Apple iPad 2.4A charging, Samsung Galaxy Tab charge schemes, and Chinese Telecom YD/T 1591-2009 - all while enabling CDP mode (1.5A charging + active USB 2.0 data communication) and low/full-speed device wake-up from S3.
For engineers reviewing the SLG55596V datasheet, SLG55596V pinout, SLG55596V application, or SLG55596V equivalent, this device serves as a system-level USB port controller for smartphone/tablet charging negotiation, host-side D+/D− switching, and intelligent current-limit switch control in portable power management subsystems.
Technical Context
The SLG55596V integrates dual-channel USB 2.0 analog switches (TDP/TDM) with on-resistance of 4.0 Ω (typ), flatness of 0.5 Ω (typ), and on-capacitance of 4.0 pF (typ), enabling full-speed/low-speed signal integrity. Its internal FSM logic implements multi-standard charger identification - including D+/D− short detection, set-resistor biasing for Apple devices, and SMART-CDP-controlled CDP/SDP mode selection.
It features an open-drain CEN# output that asserts for 2 seconds (typ) to control external current-limit switches, and supports VDD operation from 4.5 V to 5.5 V with supply current as low as 20 μA in SDP mode. Internal resistor networks (RP1/RP2, RM1/RM2) are trimmed to ±1.3% ratio accuracy and 93.0 kΩ total resistance (typ) for precise BC1.2 voltage divider compliance.
Key Specifications

|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with standard 5 V USB VBUS rails and tolerates ±5% regulation variation. |
| On Resistance (TDP/TDM) | 4.0 Ω (typ) - minimizes insertion loss and voltage drop across USB data lines during active charging/data transfer. |
| On Resistance Flatness | 0.5 Ω (typ) - maintains consistent signal amplitude across full analog input range (0–VDD), critical for USB eye diagram integrity. |
| On Capacitance | 4.0 pF (typ) - preserves >1 GHz -3dB bandwidth and meets USB 2.0 full-speed (12 Mbps) and low-speed (1.5 Mbps) timing requirements. |
| Charger ID Standards | USB BC 1.2 Rev 1.2, Apple 2.4A, Samsung Galaxy Tab, YD/T 1591-2009 - enables single-chip support for global OEM fast-charge protocols. |
| CEN# Pulse Width | 2.0 s (typ) - provides reliable gate drive timing for external current-limit MOSFETs without requiring external timing components. |
| ESD Protection (DP/DM) | ±8 kV HBM - protects exposed USB connector pins against common handling and docking ESD events in end-user environments. |
Pinout & Package
TDFN-8 package (2 mm × 2 mm × 0.75 mm) with exposed thermal pad connected to GND for enhanced thermal dissipation in compact portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 CEN# | P-FET open-drain output | Asserts low for ~2 s to enable external current-limit switch; requires pull-up for logic-high idle state. |
| 2 DM | USB connector D− I/O | Direct connection to downstream USB device D− line; passes full-speed/low-speed differential signals with minimal distortion. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB host charger identification and analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2546RTER | Dedicated USB charger detector with integrated 5-V power switch; no analog D+/D− switching capability; supports BC1.2 only (no Apple/Samsung/YD/T 1591). | Limited to basic SDP/CDP/DCP detection without data-path routing - requires external USB switches for full functionality. | Choose TPS2546RTER if only charger ID is needed and D+/D− switching is handled elsewhere; not suitable as direct functional replacement for SLG55596V. |
| IP5306 | Single-chip power bank SoC with integrated Li-ion charger, boost converter, and BC1.2 detection; lacks USB 2.0 analog switches and CEN# control output. | Designed for portable power banks, not host-side USB port management; no support for host transceiver interface (TDP/TDM). | Choose IP5306 for self-contained power bank designs; SLG55596V remains required for host-based USB port intelligence with signal routing. |
Compared with TPS2546RTER and IP5306, the SLG55596V uniquely combines BC1.2/Apple/Samsung/YD/T 1591 identification, USB 2.0 analog switching, and programmable CEN# control in one TDFN-8 package - enabling compact, firmware-free host port solutions where data path integrity and multi-standard charging coexist.

FAQ
What is the primary function of the SLG55596V in a USB host system?
The SLG55596V serves as a USB host-side charger identification and analog switching IC. It automatically detects connected device charging standards (USB BC1.2, Apple, Samsung, YD/T 1591), controls external current-limit switches via its CEN# output, and routes D+/D− signals between host transceivers and USB connectors using low-RON, low-COFF analog switches - all without firmware intervention. The SLG55596V enables robust, standards-compliant USB port power management in space-constrained designs.
Does the SLG55596V support USB 2.0 high-speed (480 Mbps) data transfer?
No, the SLG55596V is specified for low-speed (1.5 Mbps) and full-speed (12 Mbps) USB 2.0 operation only. Its 1 GHz -3dB bandwidth and 4.0 pF on-capacitance meet full-speed requirements but do not guarantee high-speed signal integrity. The SLG55596V is intended for charging negotiation and basic data communication - not high-bandwidth applications like video streaming or mass storage. For high-speed support, a dedicated USB 2.0 high-speed switch is required alongside the SLG55596V.
How does the SMART-CDP pin affect SLG55596V behavior when CB = 1?
When CB = 1, the SLG55596V enters mode-select configuration: if SMART-CDP = 0, it forces SDP-only mode (500 mA, data enabled); if SMART-CDP = 1, it enables CDP mode (1.5 A + active USB 2.0 data). This allows deterministic selection of charging profile without relying on autodetection timing. The SLG55596V maintains this mode until CB or SMART-CDP changes, and will revert to SDP during handshake if a non-CDP device is detected - ensuring backward compatibility while maximizing data throughput where supported.
What is the purpose of the CEN# output on the SLG55596V, and how is it used?
The CEN# output is an open-drain P-FET driver that asserts low for approximately 2 seconds (typ) to enable external current-limit switches during charger detection and mode establishment. It is synchronized to CB transitions and provides precise timing for gate control of N-channel MOSFETs in the VBUS path. The SLG55596V uses CEN# to eliminate external timing components, reducing design complexity. A pull-up resistor is required on CEN# to define its inactive (high-impedance) state, and the SLG55596V does not drive CEN# high internally.
Can the SLG55596V be used in automotive applications?
No - the SLG55596V is explicitly qualified for the consumer market only, as stated in the datasheet: "THIS PRODUCT HAS BEEN DESIGNED AND QUALIFIED FOR THE CONSUMER MARKET. APPLICATIONS OR USES AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS ARE NOT AUTHORIZED." Its operating temperature range (−40°C to +85°C) and qualification level do not meet AEC-Q100 requirements. For automotive USB port management, designers must select AEC-Q100-qualified alternatives; the SLG55596V is not recommended or warranted for automotive use.
