Overview
The TSM1012IDT is a low consumption voltage and current controller designed for switch-mode power supply applications requiring constant voltage and constant current modes. It integrates one voltage reference and two operational amplifiers with ORed outputs. The device operates within an input voltage range of 4.5 V to 28 V, with a maximum operating temperature of +105 °C and a minimum of -40 °C. It features a fixed output voltage reference of 1.25 V with 0.5% and 1% precision options. The quiescent current is 100 uA, and the output current capability is 10 mA. It is housed in an SOIC-8 package.
Feature Summary
- Integrates a voltage reference and two operational amplifiers with common collector outputs for combined voltage and current control.
- Provides high AC mains voltage rejection and easy compensation capabilities.
- Features a current sink output stage suitable for direct drive applications.
Applications
- Battery chargers
- Adapters
- Switch-mode power supplies
Procurement Notes
Verify the specific suffix IDT indicates tape and reel packaging when ordering. Confirm RoHS compliance status through official documentation as requirements vary by region. Ensure moisture sensitivity level handling procedures are followed during assembly to prevent damage. Check for lead-free standards if required by local regulations. Validate that the SOIC-8 package dimensions match the target PCB footprint.
Selection Notes
Select this component for designs requiring integrated CV/CC control without external op-amps. Consider the 4.5 V to 28 V input range for compatibility with various bus voltages. Evaluate the 100 uA supply current for low-power efficiency requirements. Verify thermal performance at the maximum 105 °C junction temperature. Compare against discrete solutions for board space savings.
Part Context
The TSM1012 belongs to the TSM1012 series of current and power monitors and regulators from STMicroelectronics. It is categorized under PMIC - Power Management ICs. The device is part of a family including variants like TSM1012ID and TSM1013AIDT, which share similar functional blocks but may differ in specific electrical characteristics or packaging options.
