JMS539 PDF – USB to SATA II 3.0G Bridge Controller

Posted on by pinout

This post explains for the bridge controller. A USB to SATA II 3.0G bridge controller is an integrated circuit or controller chip that serves as an interface between a USB (Universal Serial Bus) port and a SATA II (Serial ATA) storage device. It enables the connection of SATA II hard drives or solid-state drives (SSDs) to a computer or other device via a USB interface.

The Part Number is JMS539.

The function of this semiconductor is SuperSpeed USB to SATA II 3.0G Bridge Controller.

Manufacturer: JMicron

Description

The JMS539 is a bridge controller, which translates the communication protocol between SATA II 3.0G and SuperSpeed USB commands. The integrated 60MIPS 8051, SATA II, Hi-Speed USB and SuperSpeed USB technology enable users to perform SuperSpeed USB to SATA II 3.0G, applications in a signal chip.

In this chip, the Hi-Speed/SuperSpeed USB controller supports the USB Mass Storage Class Bulk-Only
Transport Specification.

USB to SATA II 3.0G bridge controllers are commonly used in external hard drive enclosures, docking stations, or adapter cables that enable the connection of SATA II storage devices to computers or other devices with USB ports. They provide a convenient and efficient way to access and utilize SATA II storage devices via USB interfaces.[…]

Description

J380 is P Channel MOS Type Field Effect Transistor.

A P-channel MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a type of field-effect transistor that uses P-type semiconductor material for its channel. It is one of the two main types of MOSFETs, with the other being the N-channel MOSFET that uses N-type semiconductor material for its channel.

In a P-channel MOSFET, the channel is formed between the drain and source regions within a P-type substrate. The operation of a P-channel MOSFET is controlled by applying a voltage to the gate terminal, which creates an electric field that modulates the flow of charge carriers (holes) in the P-type channel region.

Features

1. 4-V gate drive

2. Low drain-source ON resistance: RDS (ON) = 0.15 Ω (typ.)

3. High forward transfer admittance: |Yfs| = 7.7 S (typ.)

4. Low leakage current: IDSS = −100 μA (max) (VDS = −100 V)

5. Enhancement mode: Vth = −0.8~−2.0 V (VDS = −10 V, ID = −1 mA)
