DS1336中文资料电池切换芯片数据手册ADI规格书

描述 Description

The DS1336 Afterburner Chip provides multiple power switching paths in battery-backed applications such as networked SRAMs. The chip's power inputs are designed to connect directly with power-fail or power-warning outputs from Dallas MicroManagers: the DS1236, DS1239, DS5001, or DS5340, which monitor software and system power in microprocessor-based systems. When a power-fail input becomes inactive, the DS1336 automatically switches from battery power back to Vcc. The DS1336 can also be configured to gradually switch from system to battery power while system power is still the greater power source. The five Vcc switches and two battery switches can be wired individually or in parallel.
The DS1336 is unique in performing heavy-duty switching with minimum power loss from the switch itself, with a low on-impedance of 0.7Ω.

特性 Features

• Five separate Vcc switches handle up to 1.5A between 3.0Vand 5.0V
• Two battery switches direct power for battery backed systems
• Very low on-impedance of 0.7Ω
• Battery backup current of 4mA
• Battery path is diode-isolated, with low voltage drop
• Maintains steady power supply in battery-backed network of SRAMs
• Operating range: 0°C to 70°C

简介

DS1336属于集成电路（IC）的OR控制器理想二极管。由制造生产的DS1336OR 控制器，理想二极管理想二极管控制器也称为 OR-ing 控制器，可用于以仅允许单向电流的方式控制外部通道晶体管（通常为 FET），类似于整流二极管，但传导损耗低得多。在其他应用中，它们通常用于在为了冗余和增加电流输出能力而并行连接的电源中提供逆流保护。
