LV5052V-TLM-E

DC DC Switching Controllers Overview

The LV5052V-TLM-E is a dual H-bridge motor driver manufactured by Sanyo Semiconductors, now part of Panasonic. This component integrates two independent bridge circuits capable of driving DC motors or stepper motors in forward, reverse, and brake modes. It features built-in protection mechanisms including overcurrent detection and thermal shutdown to ensure reliable operation under varying load conditions. The device is designed for low-voltage applications, typically operating within a supply voltage range of 2.7V to 13.5V, making it suitable for battery-powered portable electronics and small appliance control systems.

DC DC Switching Controllers Feature Summary

• Dual H-bridge architecture enabling independent control of two DC motors or one bipolar stepper motor
• Integrated overcurrent protection with latch-off functionality to safeguard against short circuits
• Thermal shutdown circuit prevents damage during excessive heat generation
• Low on-resistance output stage minimizes power loss and improves efficiency

DC DC Switching Controllers Applications

• Portable printer and scanner motor control
• Small home appliance fan and pump drivers
• Battery-operated robotic vehicle chassis control
• Industrial automation relay and solenoid switching

DC DC Switching Controllers Procurement Notes

Verify the manufacturer origin as Sanyo Semiconductors (Panasonic) due to historical brand transitions. Confirm the suffix -TLM-E indicates the specific tape-and-reel packaging variant. Check for RoHS compliance status if environmental regulations apply to your assembly process. Ensure the ordering code matches the exact pinout and thermal pad configuration required by your PCB layout.

DC DC Switching Controllers Selection Notes

Select this component when dual-channel motor control is required in a compact surface-mount package. Consider its current handling capabilities relative to your motor's stall current requirements. Evaluate the need for external flyback diodes if the load inductance exceeds the internal protection limits. Compare thermal performance metrics against ambient operating temperatures to determine if additional heatsinking is necessary for sustained duty cycles.

DC DC Switching Controllers Part Context

This part belongs to the LV series of motor driver ICs developed by Sanyo, which were widely adopted in consumer electronics before the company's semiconductor division was acquired by Panasonic. The LV5052V specifically targets applications requiring simple interface control via standard logic inputs. Its design philosophy emphasizes ease of use with minimal external components while providing robust protection features essential for unattended operation in consumer devices.
