BQ25185DLHR 是德州仪器(TI)推出的一款适用于单节锂系电池的独立线性充电管理芯片,集成电源路径管理并支持太阳能输入。该器件可在宽输入电压范围内工作(3V–18V),最大充电电流为1A,静态电流仅约4µA,适合空间受限、对待机耗电极其敏感或需接入可变光伏电源的便携与遥测类产品。
作为线性充电器,器件的功耗主要由 (Vin - Vbat) × Icharge 决定。在输入电压高且充电电流大的工况下,芯片会产生显著热量。例如,当 Vin 为 12V,而电池端为 4.2V 且充电电流为 1A 时,器件耗散约 7.8W;若 Vin 更高(接近 18V),耗散更大。设计时务必:
总结:BQ25185DLHR 以其单节线性充电、低静态电流与太阳能友好特性,适合对尺寸、静态功耗与输入容错性有较高要求的电池供电系统,但在高输入电压或高功率充电场景必须重视热管理与电池化学匹配。欲获得完整设计规范及参数,请结合 TI 官方数据手册进行详细核对与仿真。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
