LDS6203NTGI

Overview

The LDS6203NTGI is a DMOS Full Bridge Driver designed for motor control applications, realized in Multipower-BCD technology. This mixed-signal integration combines isolated DMOS power transistors with CMOS and Bipolar circuits on a single chip to optimize logic circuitry and the power stage. The device features DMOS output transistors capable of operating at supply voltages up to 48V and efficient high-speed switching. All logic inputs are compatible with TTL, CMOS, and microcontrollers. Each half-bridge channel is controlled by a separate logic input, while a common enable signal controls both channels simultaneously.

Feature Summary

• High efficiency operation through optimized Mixed Technology BCD integration
• Integrated cross-conduction protection and thermal shutdown mechanisms
• TTL, CMOS, and microcontroller compatible logic inputs

Applications

• Motor control systems requiring full bridge driver topology
• Industrial automation equipment utilizing high-speed switching
• Applications demanding robust thermal and cross-conduction protection

Procurement Notes

Verify the specific suffix NTGI against official Renesas documentation to confirm package type and temperature grade. Ensure compatibility with system voltage requirements not exceeding 48V. Cross-reference pinouts with the latest datasheet revision to prevent interface mismatches during integration.

Selection Notes

Select this component when a fully integrated full bridge solution is required for motor drives. It is suitable for designs needing high switching frequencies up to 100 kHz. Consider the typical RDS(on) of 0.3 Ω at 25°C for thermal management planning. Verify that the load current does not exceed the 4A RMS rating.

Part Context

This part belongs to the L6203 series of DMOS Full Bridge Drivers from Renesas Electronics Corporation. The series utilizes Multipower-BCD technology to combine power and logic functions. It serves as a direct replacement or upgrade for legacy discrete bridge solutions in compact motor control form factors.

Replacement Considerations

Consult official Renesas cross-reference tools for verified substitutes. Ensure any alternative maintains the 48V supply capability and 4A RMS current rating. Verify pinout compatibility if replacing directly in existing PCB layouts.
