Mingjiada Supply ADI LTC2955 Micropower Pushbutton On/Off Controller

Shenzhen Mingjiada Electronics Co., Ltd. — Long-term supplier of the [ADI] LTC2955 – a micropower pushbutton on/off controller. This device features an automatic enable function and supports a wide input voltage range from 1.5V to 36V. It is suitable for applications such as desktop and laptop computers, GPS devices, portable instruments and automotive electronics.

What is the LTC2955?
The LTC2955 is a micropower pushbutton on/off controller that generates a clean enable output to manage the system power supply via a power monitor input and a debounced pushbutton input. The device features an interrupt output that signals the system when the pushbutton is triggered or when the power supply voltage is low. When the system is in a ready state, it can use the power-off input to switch off the power supply. If a button is held down for longer than the configurable power-off timeout, the system power supply will be forcibly switched off.

Key Features of the LTC2955:
Automatic power-on via the voltage monitor input
Wide input supply voltage range: 1.5V to 36V
Low supply current: 1.2 μA
±25 kV ESD HBM protection provided on the PB input
±36 V wide input voltage range for the PB input
Low-leakage EN output for DC/DC converter control (LTC2955-1)
High-voltage EN output for driving an external P-channel MOSFET (LTC2955-2)
A simple interface enables seamless microprocessor (μP) shutdown
Adjustable shutdown timer
10-pin 3mm x 2mm DFN package and 8-pin ThinSOT™ package
