LB1857M-TLM-E

Overview

The LB1857M-TLM-E is a dual DC motor driver manufactured by onsemi, designed for automotive applications. It operates within a supply voltage range of 4.5 V to 16 V and supports continuous output currents up to 2.0 A per channel. The device features an MFP-20 package and functions across a temperature range of -20°C to +70°C. Key electrical parameters include a maximum operating voltage of 16 V and a quiescent current typical of low-power automotive ICs.

Feature Summary

• Integrated dual H-bridge configuration for bidirectional motor control
• Built-in protection mechanisms against overcurrent and thermal overload
• Compatible with standard logic inputs for easy interface with microcontrollers

Applications

• Automotive power window systems
• Seat adjustment actuators
• Sunroof and convertible top drives

Procurement Notes

Verify the specific suffix 'TLM' confirms the tape-and-reel packaging format and lead-free status as per the manufacturer's latest datasheet revision. Confirm RoHS compliance documentation is available for your region's regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a compact dual-channel solution is required for low-to-medium power DC motors in automotive environments. Ensure the thermal management design accounts for the MFP-20 package limitations under continuous load conditions at higher ambient temperatures.

Part Context

This part belongs to onsemi's automotive-grade discrete and small-signal transistor portfolio, specifically tailored for body electronics. It complements other motor drivers in the series by offering a balance of performance and cost-effectiveness for non-critical motion control tasks in vehicles.

Replacement Considerations

Check for direct pin-compatible alternatives such as the LB1857M series variants or equivalent parts from other manufacturers like NXP or STMicroelectronics that meet the same 16V/2A specifications and automotive qualification standards.
