IR2104STRPBF-JSM 产品概述

一、简介

IR2104STRPBF-JSM 是一款双通道高边/低边 MOSFET 驱动器,面向需要可靠栅极驱动能力的功率电路设计。器件采用 SOIC-8 封装,集成欠压保护(UVP),适用于以 MOSFET 为负载的半桥及全桥驱动场合,品牌为 JSMSEMI(杰盛微)。

二、主要参数一览

  • 工作电压:10 V ~ 20 V
  • 驱动通道数:2(高边 + 低边)
  • 拉电流(IOH,源极能力):300 mA
  • 灌电流(IOL,吸收能力):600 mA
  • 上升时间(tr):75 ns
  • 下降时间(tf):35 ns
  • 静态工作电流(Iq):120 μA
  • 工作温度范围:-40 ℃ ~ +125 ℃
  • 特性:欠压保护(UVP)
  • 封装:SOIC-8

三、功能要点说明

  • 欠压保护(UVP):在供电电压低于设定阈值时自动禁止输出,避免栅极处于半导通状态而导致 MOSFET 发热或失效,提升系统可靠性。
  • 高/低边驱动:支持同时驱动高侧与低侧 MOSFET,适合半桥拓扑;若用于高侧浮动驱动,需配合引导(bootstrap)或独立浮动供电方案。
  • 驱动能力不对称:600 mA 灌电能力强于 300 mA 拉电能力,这在关断瞬态中能更快速将栅极拉低,减少死区时间内的交穿风险。
  • 快速开关特性:75 ns 上升与 35 ns 下降时间适合中高速开关场合,但具体开关速度仍受负载电容与外接栅阻影响。

四、典型应用场景

  • 12 V 车载或工业控制系统的半桥/全桥 MOSFET 驱动(在允许的电压范围内)
  • DC-DC 变换器、逆变器与电机驱动控制板的栅极驱动单元
  • 开关电源、LED 驱动与各种功率开关模块的外围驱动电路

五、封装与布局建议

  • SOIC-8 封装利于通用 PCB 布局,注意热量主要通过引脚和印制电路板散发,必要时在 PCB 下方增加铜箔以增强散热。
  • 靠近器件放置去耦电容(尤其是高边浮动供电或 bootstrap 电容),低电感走线确保瞬态电流的稳定供应。
  • 输出端(栅极)到 MOSFET 栅极之间建议串联小阻(栅阻)以控制开关速度、抑制振铃并限制电流冲击。

六、设计注意事项

  • 若采用高侧浮动驱动,需正确设计 bootstrap 电路或提供稳健的浮动供电,保证在整个开关周期内高边驱动电压充分。
  • 依据 MOSFET 门电荷选择合适的驱动速率与栅阻,防止过快开关引起 EMI 或器件应力。
  • 考虑器件的欠压保护特性对系统启动顺序的影响,必要时在系统中加入合适的上电复位或延时逻辑。
  • 在高温或高频应用场景下,关注 SOA 与热升高,必要时进行热仿真与散热设计。

总结:IR2104STRPBF-JSM 为一款面向 MOSFET 驱动的双通道高/低边驱动器,具备欠压保护、较强的灌电能力与快速开关响应,适用于中功率开关电源、半桥驱动与电机控制等场合。具体参数与应用细节请结合实际电路和器件数据表进行验证与优化。

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
