Ultra-Efficient, I_QSmart™ Protected PowerSwitch Technology

The GLF System Power Protection Switch Family include Deep Sleep protection devices and features indutry lowest ON Resistances, Quiescient and Standby currents as well as the best system protection features. 

The Deep Sleep Switch enables a system to enter ultra-low power conservation mode by disconnecting the battery, with the ultra-low standby current of 7nA typical. With the switch placed between a battery and system, the device significantly extends system battery life in mobile devices during shipping or periods of extended "off" times. The part supports user (push button) and software initiated events. The device has an internal debouncing circuitry. 

The Power Reset Switch offers a true power reset function by disconnecting the battery after a reasonably long delay time. After the reset period, the main switch of the GLF76121 / GLF76121L reconnects the output load to the input battery for normal operation. The GLF76121 offers 5.8 second delay time before the 360ms reset duration while the GLF76121L has 11.6 second delay time and then 700ms reset time. The OFF input pin allows the GLF76121 / GLF76121L to achieve complete shutdown with a total downstream standby current of 7nA typical.

An ideal battery protection switch would draw zero current when the application is in standby mode.
We believe GLF’s IQSmart™ battery protection switches are the closest you can get to perfection.

Our ultra-efficient and compact battery protection switches not only offer ultra-low leakage current – up to 50 times lower than other similar switches – they also exhibit the lowest R_DS(ON) for a given small form factor.

GLF's power Mux (Power Multiplexer) designs are optimized for simplicity of installation and use. They are ideal for wearables and other small form factor systems, where space and component count is a premium. 

A power Mux selects  between mulitple power sources on its input, to provide a single power rail on its output. Traditional input power rails may include a charger and a battery, an aux and main battery, or two chargers: one wired and one wireless.

GLF offers a uniquely simple power mux solution, that requires no external components to control power selection. A typical power mux requires outside monitoring and processing to decide which power rail to select. There is no space for this in an ultra small wearable. GLF power mux designs offer a single low IQ chip that self selects its power source, and is specifically designed to require no external componets, monitoring, or extra processor pins to operate. Its a true place and forget solution.

It is an advanced technology fully integrated power switch for various USB applications demanding precision output current limit. It features several protection functions such as under voltage lockout, true reverse current blocking (TRCB), short circuit protection, and thermal shutdown. It is ideal for reliable protection applications on critical power rails to downstream system. It provides multiple options to meet diversified technical demand in real system design.

 The AEC-Q100 qualified ICs are rated for a wide temperature range (Grade 1 -40°C to +125°C).

Applications include infotainment and cluster display systems, diagnostic systems, passive entry/start systems (PEPS), customer premise equipment (CPE), face recognition systems and intelligent cockpit and autonomous driving applications.

Each load switch IC supports a wide-input voltage range (1.5V to 5.5V), meaning a single device can be used in a variety of voltage rail applications, which helps to simplify inventory management. And both are offered with an optional output discharge switch.

Switching regulators are the most efficient way to convert one DC voltage to another DC voltage.  GLF DC/DC parts have a lots of protection functions, such as OTP/OCP/OVP/UVP/SCP, which can improve the switching regulator’s function performance and reliability. GLF’s DC/DC parts are low power consumption and high quality which are your ideal choice.
