TLE4205G Equivalent & Substitute Parts

Part Overview

The TLE4205G is a brushed DC motor driver IC manufactured by Infineon Technologies, designed for applications requiring fully integrated control and power stage functionality. Operating across a 6V to 32V supply range with 1A output current capability, this component integrates both control logic and power switching in a single package. The TLE4205G is classified as obsolete, necessitating identification of functionally equivalent alternatives for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE4205G is determined by the following critical parameters:

• Output Configuration: Half Bridge (2) topology
• Motor Type: Brushed DC motor driver capability
• Function: Fully integrated control and power stage
• Interface: Parallel control interface
• Technology: Bipolar implementation
• Output Current: Minimum 1A capability
• Supply Voltage Range: Overlap with 6V ~ 32V operating window
• Mounting Type: Surface mount compatibility

Substitute parts are grouped based on voltage operating range compatibility and current rating sufficiency. Parts with lower voltage ranges (4.5V ~ 16V or 3V ~ 9V) are suitable only for applications operating within those reduced ranges. Parts with lower current ratings (500mA or 400mA) are suitable only for applications requiring reduced output current.

Parameter Comparison

Engineering Selection Recommendations

Full Voltage Range Compatibility (6V ~ 32V): No substitute parts maintain the complete 6V to 32V supply voltage range of the TLE4205G. Applications requiring operation across this full range cannot be directly substituted without circuit redesign.

Partial Voltage Range Compatibility:

• TA7267BP(O): Operates 6V ~ 18V, covering the lower portion of the TLE4205G range. Active product status with RoHS compliance. Through-hole mounting differs from original surface-mount package.

• TA7291FG(O,EL): Operates 4.5V ~ 20V with 400mA output current. Active product status with RoHS compliance. Surface-mount package. Reduced current rating requires verification for applications demanding 1A output.

• TA7291SG(O,J): Operates 4.5V ~ 20V with 400mA output current. Active product status with RoHS compliance. Through-hole mounting. Reduced current rating requires verification for applications demanding 1A output.

Reduced Voltage Range Compatibility:

• LB11961V-TLM-E: Operates 4.5V ~ 16V with 1A output current. Active product status with ROHS3 compliance. Surface-mount package. Suitable for applications operating within 4.5V to 16V window.

• LB11961-TLM-E: Operates 4.5V ~ 16V with 1A output current. Obsolete product status with ROHS3 compliance. Surface-mount package.

• LB1830MC-AH: Operates 3V ~ 9V with 500mA output current. Obsolete product status with ROHS3 compliance. Surface-mount package. Reduced current and voltage range limit applicability.

Compliance Considerations: All substitute parts except TLE4205G are RoHS compliant. Applications requiring RoHS non-compliant components must retain the original TLE4205G or verify compliance requirements with design specifications.

Frequently Asked Questions (FAQ)

Q: Can LB11961V-TLM-E directly replace TLE4205G in all applications?

A: LB11961V-TLM-E is suitable only for applications operating within the 4.5V to 16V supply range. Applications requiring operation above 16V cannot use this substitute without circuit modification.

Q: What is the difference between LB11961-TLM-E and LB11961V-TLM-E?

A: Both parts operate at identical voltage and current specifications (4.5V ~ 16V, 1A output). LB11961V-TLM-E is active product status in 16-SSOP package, while LB11961-TLM-E is obsolete in 14-HSSOP package. LB11961V-TLM-E is recommended for new designs.

Q: Why do TA7291FG and TA7291SG have reduced current ratings?

A: These parts are specified for 400mA maximum output current, compared to TLE4205G's 1A rating. Applications requiring 1A output current cannot use these substitutes.

Q: Are the Toshiba parts suitable for automotive applications?

A: TLE4205G carries automotive grade designation. Substitute parts do not specify automotive grade. Automotive application requirements must be verified against specific part datasheets and qualification status.

Q: What mounting considerations apply when selecting a substitute?

A: TLE4205G is surface mount. TA7267BP(O) and TA7291SG(O,J) are through-hole packages requiring PCB redesign. LB11961-TLM-E, LB11961V-TLM-E, LB1830MC-AH, and TA7291FG(O,EL) are surface mount, compatible with original PCB layout.

Q: Can I use LB1830MC-AH as a substitute?

A: LB1830MC-AH operates at 3V ~ 9V with 500mA output current. This part is suitable only for low-voltage, low-current applications within its specified range and cannot substitute for higher voltage or current requirements of the TLE4205G.
