Overview
The ST2052BDR is a dual RS-232 transceiver manufactured by STMicroelectronics, designed for low-power applications. It operates from a single 3.3 V or 5 V supply and incorporates charge pump circuitry to generate the necessary positive and negative voltages for RS-232 communication without requiring external inductors. The device features two drivers and two receivers, supporting data rates up to 120 kbps. It includes ESD protection on all pins and is available in a compact TSSOP-16 package, making it suitable for space-constrained portable electronics.
Feature Summary
- Integrated charge pump eliminates need for external inductors
- Low quiescent current for battery-powered devices
- Built-in ESD protection on all interfaces
Applications
- Portable computers and notebooks
- Handheld terminals
- Industrial control systems with serial communication
Procurement Notes
Verify the specific suffix 'BDR' corresponds to the TSSOP-16 package and tape-and-reel packaging configuration as defined in the official datasheet. Confirm that the operating temperature range and voltage specifications align with your system requirements before procurement.
Selection Notes
Select this component when a dual-channel RS-232 interface is required in a small form factor. It is appropriate for designs needing low power consumption and integrated voltage generation, avoiding the complexity of discrete charge pump circuits or external inductors found in older generations of transceivers.
Part Context
This part belongs to STMicroelectronics' line of RS-232 transceivers, specifically optimized for low-voltage operation. It complements other single and quad driver variants within the family, offering a balance between channel count and physical footprint for embedded serial communication tasks.
Replacement Considerations
Check for pin-compatible alternatives such as the ST2052C or similar dual RS-232 transceivers from other manufacturers, ensuring voltage levels and data rate capabilities meet the original design specifications.
