XC6808B3D18R-G Equivalent & Substitute Parts

Part Overview

The XC6808B3D18R-G is a single-cell lithium ion/polymer battery charger IC manufactured by Torex Semiconductor Ltd. This power management integrated circuit operates as an active product with full regulatory compliance. The device is housed in a 6-XDFN exposed pad surface mount package and delivers programmable constant-current charging at a maximum of 40mA with integrated fault protection for over-current, over-temperature, and reverse-current conditions.

Substitute parts are identified when equivalent electrical specifications, mechanical packaging, and regulatory compliance are maintained across alternative part numbers within the same manufacturer's product line. This ensures functional interchangeability in production environments and design revisions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the XC6808B3D18R-G is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Battery chemistry (Lithium Ion/Polymer)
• Single-cell configuration
• Maximum charge current (40mA)
• Battery pack voltage (4.35V)
• Maximum supply voltage (6V)
• Operating temperature range (-40°C ~ 85°C)
• Programmable current charging capability
• Identical fault protection features (over-current, over-temperature, reverse-current)

Mechanical & Packaging Specifications:

• Package type (6-XDFN Exposed Pad)
• Supplier device package designation (6-USP-B07 with 1.8x2 dimensions)
• Surface mount mounting type

Regulatory & Compliance:

• RoHS3 compliance
• REACH unaffected status
• Moisture sensitivity level (MSL 1)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. The XC680x series designation confirms product family alignment.
