Techcode Semiconductor Releases 27V High Withstand Voltage USB Type-C Current Limiting Protective Switching Chip TD9535
Recently, Techcode Semiconductor, a well-known domestic semiconductor company committed to R&D, design and sales of high-performance and high-quality analog chips, releases its first high-voltage USB Type-C current-limiting protection chip TD9535. TD9535 is a switch protection chip limited by 27V withstand voltage programmable current, and provides perfect protection function and soft start function. The device is packaged in 3*3mm DFN and is integrated with 40 milliohm high-side MOSFET, which can effectively balance the temperature rise. It is suitable for USB Type-C data cables, new laptops and other applications that are related to USB Type-C PD.
TD9535 operates from 4.5v to 24v. VIN and VOUT can support a maximal input voltage of 27V. This device is very suitable for port protection under USB PD protocol. When it is used as USB port switch protection, the programmable current limiting function in it can protect the circuits from sharp current impact. When the switch is turned off, MOSFET shields the leakage current from VIN to VOUT.
TD9535 has many adjustable protection functions: soft start, short circuit protection, overcurrent protection, undervoltage protection, overtemperature protection and fault indication.
As USB Type-C PD is more and more widely used in laptops, USB docking stations and other data transmission devices. Designers and users will expect that schemes with higher power, faster speed and better performance can be used for high-performance products in the future. low RDS(ON) and TD9535 with perfect protection function have industrial performance parameters, which makes it the most ideal intelligent switching chip for USB Type-CPD.
