- Low-power consumption design with quiescent current typically below 1 mA, extending battery run time and reducing thermal dissipation in portable charger and adapter applications
- Compact 8-pin SOP-8 (SOIC-8) package enabling space-efficient PCB integration in slim charger designs with full CV/CC control loop in a 5x4 mm body
Applications
The TSM1014IDT is designed for constant-voltage/constant-current (CV/CC) control in battery charger and power adapter circuits, including Li-ion cell phone chargers, laptop power bricks, and industrial battery management systems. Its single-channel architecture and integrated control loops simplify the feedback network, reducing external component count and PCB area in charger designs targeting 5V to 20V output rails. Smart charging docks, IoT device adapters, and USB power delivery accessories also use this controller for its low quiescent power draw and RoHS-compliant 8-pin SOIC construction.

Frequently Asked Questions
What charging topologies does the TSM1014IDT support, and what output voltage range can it regulate?
The TSM1014IDT implements constant-voltage and constant-current (CV/CC) control suitable for flyback and forward converter battery charger topologies targeting Li-ion, Li-polymer, and lead-acid battery chemistries. Its feedback network supports programmable output voltages typically in the 4V to 20V range depending on external resistor divider values, enabling flexible charger designs from 5V USB-compatible outputs to 12V or 19V laptop adapter rails in a single 8-pin SOP-8 package.
How does the TSM1014IDT reduce external component count compared to discrete CV/CC controller implementations?
The TSM1014IDT integrates both the voltage error amplifier and current sense comparator into a single 8-pin SOIC package, eliminating at least 2 separate op-amp ICs and their associated bypass capacitors from a discrete implementation. A complete CV/CC loop requires only an external current sense resistor (typically 0.1 Ohm to 1 Ohm), a feedback resistor divider, and a coupling capacitor, reducing total BOM by approximately 8 to 12 passive components versus a discrete approach.
What package does the TSM1014IDT use, and how does this affect thermal management in a compact charger design?
The TSM1014IDT is housed in an 8-pin SOP-8 (SOIC-8) package with a 5 mm x 4 mm body and 1.27 mm pin pitch. The plastic epoxy package has a typical thermal resistance of approximately 160°C/W junction-to-ambient, so at the controller's low quiescent operating power (under 50 mW self-dissipation) it operates well within limits without a heatsink. The compact footprint allows full CV/CC charger control circuitry to fit within a 15 mm x 10 mm PCB area in slim portable charger designs.
Is the TSM1014IDT suitable for a 5V/2A USB charger design, and what current sense resistor value is appropriate?
Yes, the TSM1014IDT can regulate a 5V/2A output in a flyback USB charger topology. For 2A maximum charge current, a current sense resistor of approximately 0.1 Ohm placed in the primary or secondary current path provides a 200 mV sense voltage at full load — a typical threshold for the integrated current comparator. This 0.1 Ohm resistor dissipates 0.4 W at 2A, requiring a 0.5W or 1W rated resistor to maintain reliable thermal operation within the compact 8-pin SOP-8 controller circuit.
