Littelfuse has announced the SP1255P family of low capacitance ESD protection transient suppression diode arrays (SPAs) designed to provide best-in-class ESD protection for current-intensive applications such as fast charging peripherals or power USB. The SP1255P family integrates a three-channel ultra-low capacitance steering diode and a low voltage transient suppression diode to provide maximum anti-static protection for USB data and ID pins in accordance with IEC 61000-4-2. Its dynamic resistance is only 0.3?, which reduces the clamping voltage by up to 23% compared to similar silicon solutions. A high surge current protection device operating at 12V will be used for Vbus protection; this device protects against lightning-fast transients of up to 100A on USB Vbus lines.
Typical applications for the SP1255P series include ESD protection for smartphones, tablets and other portable electronics.
"The SP1255P series uses a new approach to protect the charging capabilities of tablets and smartphones from high current fast transients caused by natural conditions or grid instability," said Chad Marak, director of the series of transient suppression diode arrays . "With its space-saving and small form factor, it is ideal for ESD protection applications in portable consumer electronics where board space is limited."
The SP1255P family of low capacitance ESD protection transient suppression diode arrays offers the following key benefits:
• Dynamic resistance as low as 0.3?, which reduces clamping voltage by up to 23% compared to similar silicon solutions, providing best-in-class ESD protection for current-intensive applications such as fast-charging peripherals.
• A robust ESD function protects the Vbus or USB data pins, allowing manufacturers to achieve the highest level of ESD protection than the IEC standard.
• The μDFN-6 small package (1.8x2.0x0.55 mm) simplifies PCB layout and allows routing directly under the device without the need for short lines that can cause signal degradation.
• Automotive grade quality (AEC-Q101 compliant) ensures maximum reliability in the most demanding environments.
Availability
The order quantity of the SP1255P series is 3,000. Samples are available from authorized Littelfuse distributors around the world.
Absolute rotary Encoder measure actual position by generating unique digital codes or bits (instead of pulses) that represent the encoder`s actual position. Single turn absolute encoders output codes that are repeated every full revolution and do not output data to indicate how many revolutions have been made. Multi-turn absolute encoders output a unique code for each shaft position through every rotation, up to 4096 revolutions. Unlike incremental encoders, absolute encoders will retain correct position even if power fails without homing at startup.
