HT7050S 是 UMW(友台半导体)推出的一款低功耗电压检测器(复位IC),用于对单路电源电压进行监测并在电源低于设定阈值时产生有效低电平复位信号。器件采用 SOT-23 封装,工作电压范围宽(1.5V 至 12V),内部设计简洁、静态电流极低(Iq ≈ 2 μA),非常适合电池供电或对待机功耗要求严格的嵌入式系统。
HT7050S 在内部对输入电压进行比较。当被监控的电压低于内部设定阈值(5 V)时,输出端(开漏)被拉低,产生有效的复位信号(低电平)。当电压回升并稳定超过阈值后,开漏输出释放,外部上拉电阻将输出拉高,系统退出复位状态。由于输出为开漏结构,器件可方便地与不同电压域的微控制器或多个复位线共用,但需在输出侧配置上拉电阻或连接到目标电源的上拉网络。
HT7050S 设计上着重于极低静态电流,适用于长时间待机或节电模式的场景。其宽工作电压保证了在多种供电环境下(如单节/多节电池、单芯片供电、5V 或 12V 轨)都能稳定工作。
典型 SOT-23 三引脚用途(请以正式数据手册为准):
推荐典型接法:
示意连接(逻辑): VCC — HT7050S(VCC) GND — HT7050S(GND) HT7050S(/RST) — 上拉 R — VCC RST — MCU_RST 输入
HT7050S 以其宽电压适应性、超低静态电流与简洁的功能,适合作为常见的上电/欠压复位方案。在设计时请严格参考官方数据手册进行阈值容差、时序与典型曲线的校对,并根据系统实际噪声与时序需求调整上拉、电容及PCB布局。
Request for quote
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.
