Ideal diode and battery has the following characteristics
1. When the output / load current input current limit, or more than Laptop Battery dell laptop battery when the input power was removed, an ideal diode components from the battery to provide power;
2. Ideal diode (rather than directly connected to a battery load) load to the power supply to enable a full charge the battery in the external power supply was removed before the full charge to keep, and make the device even in a fully depleted The battery case was also able to work;
3. Once the external power supply is removed dell laptop battery Laptop Battery, the output voltage drop, until the ideal diode forward bias was imposed so far. Canada has been a positive bias will be followed by an ideal diode batteries to provide power to the load;
4. If the battery is the only available power supply or load current exceeds the input current limit has been set up, the battery will be laid in a BAT and the OUT pin 5081Pbetween the ideal diode circuits automatically transfer power to the load;
5. Ideal diode Inspiron 700m(as well as the OUT pin on the recommendation of the capacitor) IC can be made without the use of a large body of the capacitor to deal with a large transient load and the AC adapter or USB VBUS connect / disconnect BAT3151L8 mode;
6. Low loss ideal diode by reducing power and the path of the IR drop extended battery run timeInspiron 710m.
Linear Technology’s power management devices to address the above-mentioned series of IC design problems. In this area, has two main features of the new product is the LTC4085 USB power Latitude X300 management and high-voltage power LTC4089’s battery charger Manager
USB Power Manager - LTC4085
LTC4085 is a portable USB devices for theF5136 monolithic autonomous power manager, ideal diode controller and independent-linear battery charger. LTC4085 with PowerPath control feature from the USB VBUS or AC power adapter to W0465 power the system load, and single-cell lithium ion / polymer rechargeable batteries. With USB current limit specifications with, LTC4085 will be in the system load current increases automatically reduce the battery charge current. In order to ensure a full battery charge in the bus when the connection has not been used in the state of the IC through the USB bus to transfer power to the load, and the312-0306 lack of access to power from the battery. Once the power has been removed, the current through an internal low loss ideal diode 200mΩ from the battery to the load flow, thus minimizing the pressure drop and power consumption. Provides for an optional external drive GATE PFET devices to connect the circuit board, so that the application needs to ideal diode impedance312-0305, the total fell Inspiron 2000 below 30mΩ.
