MEZS7-PDCharger-MP2761

425kHz, Bidirectional PD Charger Solution with Fully Integrated Buck-Boost Charger for 2 Cells to 4 Cells in Series Evaluation Board

详情

The MEZS7-PDCharger-MP2761 is a solution module for dual-role port (DRP) applications using the MP2761 and MPF52002.

The MP2761 is a 4V to 22V input voltage (V_IN) buck-boost charger IC designed for battery packs with 2 cells to 4 cells in series. It also supplies a wide voltage range (5V to 21V) at the IN pin in source mode, which is compliant with USB power delivery (PD). It also has an output current (I_OUT) limit with a high resolution in source mode.

The MPF52002 is a highly integrated USB PD controller for DRP ports, with a 32-bit ARM Cortex-M0 microcontroller unit (MCU). It supports automatic DRP toggling for DRP applications, and is compliant with PD3.1 specifications. For source mode, the MPF52002 supports PD 3.1, BC 1.2, Apple divider mode, Huawei FCP/SCP, and QC 2.0/3.0.

The MEZS7-PDCharger-MP2761 contains a DRP USB Type-C port, supporting PD 3.1 and BC 1.2 protocols. When an adapter is inserted, the port acts as a sink port to charge the battery with a maximum 6A charge current. When a load is inserted, the port acts as a source port to power the USB VBUS from the battery.

MP2761 I²C 接口控制、2至4节电池升降压充电器IC，带NVDC 电源路径管理功能

MP2761 是一款专为 2 至 4 节串联电池组设计的升降压充电器 IC。该器件支持 4V 至 22V 的宽输入电压 (VIN) 范围内为电池充电。其升降压拓扑结构允许电池电压高于或低于 V_IN。

当接入输入电源时，MP2761 工作在充电模式。它会测量电池电压，并分四个阶段为电池充电：恒流涓流充电、恒流预充电、恒流快速充电和恒压充电。此外还提供充电截止和自动再充电功能。

MP2761 集成了输入电流 (I_IN) 限制和 V_IN 限制功能，可避免输入电源过载，符合 USB 供电 (PD) 规范。

MP2761 还提供窄电压直流 (NVDC) 电源路径管理功能。它通过集成 N 沟道 MOSFET 驱动器 (BGATE) 控制外部 N 沟道 MOSFET (BATFET)，以调节系统最低电压并提供电池补充功能。当启用源模式时，该器件通过IN 引脚可提供4V 至 21V的宽输入电压范围，此外还提供高分辨率IN 输出电流限制 (I_{IN_SRC}) 功能。这些功能均符合 USB PD 规范。

MP2761 通过 I²C/SMBus 接口配置充电和放电参数，包括 I_IN 限值，V_IN 限值、充电电流、电池满电调节电压、源模式下的 IN 输出电压 (V_{IN_SRC})和 I_{IN_SRC}。MP2761 还利用 I²C/SMBus 寄存器提供状态和故障相关信息。

为确保安全运行，MP2761可将芯片温度限制在可配置阈值范围内；除此之外，还提供其他安全功能，包括输入过压保护 (OVP)、电池过压保护 (OVP)、系统过压保护 (OVP)、过温关断，以及可配置定时器以防止失效电池长时间充电。

MP2761 采用 TQFN-30 (4mmx5mm) 封装。
