Overview
The TSM1012IST is a low consumption voltage and current controller designed for battery chargers and adapters. It integrates one voltage reference and two operational amplifiers with ORed outputs, enabling constant voltage and constant current control in SMPS applications. The device operates within an input voltage range of 4.5 V to 28 V and features a fixed output voltage reference of 1.25 V with high precision. It supports high AC mains voltage rejection and requires minimal external components.
Feature Summary
- Integrates a voltage reference and dual operational amplifiers for combined voltage and current regulation
- Provides constant voltage and constant current control modes suitable for switch-mode power supplies
- Features a current sink output stage with easy compensation capabilities
Applications
- Battery charger systems requiring precise regulation
- AC-DC adapter designs
- Switch-mode power supply (SMPS) applications
Procurement Notes
Verify the specific suffix 'IST' against the manufacturer's official documentation to confirm package type and temperature grade compatibility. Ensure the component meets RoHS requirements for your target market. Cross-reference the datasheet revision date to confirm pinout and electrical characteristics match your design specifications before finalizing procurement.
Selection Notes
Select this component when designing compact power management circuits that require integrated voltage and current limiting functions. It is suitable for applications needing low external component counts and high AC line rejection. Consider its operating temperature range and SOIC-8 packaging constraints during layout planning.
Part Context
This part belongs to the TSM1012 series from STMicroelectronics, categorized under Current and Power Monitors & Regulators. It serves as a specialized PMIC solution for managing charging profiles in portable electronics and power adapters, distinguishing itself through integrated analog control blocks rather than digital interfaces.
Replacement Considerations
Consult official substitution lists for compatible alternatives within the same product family or equivalent functional devices from other manufacturers. Verify pin-to-pin compatibility and electrical parameter alignment before replacing.
