LB1837M-TLM-E

Full Half-Bridge (H Bridge) Drivers Overview

The LB1837M-TLM-E is a monolithic linear integrated circuit designed as a low-voltage, low-saturation bidirectional constant-voltage regulated motor driver. It features two output channels capable of delivering up to 250 mA of output current with a saturation voltage of 0.40 V at that load level. The device operates within a wide supply voltage range from 3.0 V to 9.0 V and consumes minimal standby current of 0.1 μA or less. It is housed in a compact MFP14S surface-mount package suitable for portable equipment.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the exact ordering suffix and manufacturer part number against official onsemi documentation before procurement. Confirm availability status as distribution channels may list obsolete or discontinued inventory. Ensure the component meets RoHS compliance requirements specified in the datasheet. Cross-reference the MFP14S package dimensions with your PCB layout constraints. Validate electrical parameters against your system's absolute maximum ratings.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component for applications requiring bidirectional motor control with low voltage drop characteristics. The built-in constant-voltage regulation simplifies design by removing external feedback loops for speed control. Consider the MFP14S package size for space-constrained portable designs. Evaluate the 0.1 μA standby current for battery-powered systems requiring long sleep modes. Ensure the operating temperature range aligns with your environmental specifications.
