TSM1013ID

Overview

The TSM1013ID is a constant voltage and constant current controller designed for battery charger applications. It incorporates a high-stability series band gap voltage reference, two ORed operational amplifiers, and a current source. The device compares the DC voltage and current level at the output of a switching power supply to an internal reference, providing feedback through an optocoupler to the primary side PWM controller. It operates within a supply voltage range of 4.5 V to 28 V and supports surface mount installation in an SOIC-8 package.

Feature Summary

Integrates a high stability series band gap voltage reference with built-in current generator
Features two operational amplifiers with ORed output for precise control loop management
Provides optocoupler feedback capability to modify current limitation levels via offset adjustment

Applications

Battery charger controllers
Switching power supply voltage and current regulation
Primary side PWM controller feedback circuits

Procurement Notes

Verify the specific suffix 'ID' corresponds to the SOIC-8 tube packaging variant rather than tape and reel options. Confirm RoHS compliance status as it varies by manufacturing batch and region. Ensure the operating temperature range meets the -40°C to 105°C requirement for your specific application environment before finalizing procurement.

Selection Notes

Select this component when designing isolated flyback or forward converters requiring precise CC/CV profiles. The integrated ORed op-amps simplify error amplifier design compared to discrete solutions. Consider the 28 V maximum supply limit and ensure the external components support the required current sensing resolution for the target battery chemistry.

Part Context

This part belongs to the TSM101 family of analog power management ICs from STMicroelectronics. The family includes variants like TSM101 and TSM101A, which share similar functional blocks but may differ in precision, temperature ranges, or packaging options. The TSM1013ID specifically targets the 28 V input range market segment.
