LTC2955IDDB-1#TRMPBF概述

    Introduction to the LTC2955 Pushbutton On/Off Controller
    The LTC2955 is a highly efficient and micropower pushbutton on/off controller manufactured by Linear Technology (now part of Analog Devices). Designed to manage system power effectively, this device integrates multiple functionalities, including pushbutton on/off control, automatic turn-on via a voltage monitor input, and power fail indication. Key features include a low supply current of 1.2 µA, a wide input supply range from 1.5V to 36V, and robust protection against voltage spikes and ESD events.
    Product Specifications
    The LTC2955 supports a broad range of operational parameters and environmental conditions:
    | Parameter | Minimum | Typical | Maximum | Units |

    | Input Voltage (VIN) | 1.5 36 | V |
    | Power Fail Threshold (VUVL) | 1.0 | 1.15 | 1.3 | V |
    | Power Fail Hysteresis | 30 | 85 | 200 | mV |
    | Enable Output (EN) | – | 1.5–5.5 | VIN–1.5 | V |
    | Pull-Up Resistance (RPU) | 0.45 | 0.9 | 1.35 | MΩ |
    Other notable characteristics include:
    - Operating Temperature Range: -40°C to 85°C
    - ESD Protection: ±25kV human body model
    - Package Options: 10-Lead (3mm x 2mm) Plastic DFN and 8-Lead Plastic TSOT-23
    Unique Features and Advantages
    The LTC2955 offers several standout advantages that make it an ideal choice for modern electronic systems:
    1. Efficient Power Management: The low 1.2 µA supply current ensures prolonged battery life in portable devices.
    2. Robust Input Protection: Withstanding ±36V voltage swings and ESD strikes without latchup ensures durability.
