Компоненты Описание : Complete Backup-Management ICs for Lithium and NiMH Batteries

General Description
The MAX8568A/MAX8568B backup-Battery-management ICs are complete charging and backup switchover control solutions for PDAs, Smart Phones, and other smart portable devices. They charge both NiMH and Rechargeable lithium Battery types and feature programmable charge current and termination voltage. Separate optimized charge algorithms for both lithium and NiMH cells are included on-chip.
The MAX8568A/MAX8568B also manage backup switchover from a primary power source. An accurate on chip voltage detector monitors the main supply and backs up two system supplies (typically I/O and memory) when main power falls. On-chip drivers switch external MOSFETs to disconnect the main supply from the system loads so the backup source is not drained.
Low-voltage backup cells can be stepped up by an on chip synchronous-rectified, low-quiescent-current boost converter. Additionally, a low-quiescent-current LDO generates a second backup voltage. The MAX8568A LDO is preset to 2.5V while the MAX8568B LDO is preset to 1.8V. Both devices are supplied in 16-pin 3mm x 3mm thin QFN packages rated for -40°C to +85°C operation.

Features
♦ Automatically Manage All Backup Switchover Functions
♦ Charge Both NiMH and Rechargeable Lithium Backup Batteries
♦ On-Chip Battery Boost Converter for 1-Cell NiMH
♦ Two Backup Output Voltages
♦ Programmable Charge Current
♦ Programmable Charge Voltage Limit
♦ Low 17µA Operating Current in Backup Mode
♦ Eliminate Many Discrete Components
♦ Tiny 3mm x 3mm Thin QFN Package

Applications
   PDAs and PDA Phones
   Smart Phones
   DSCs and DVCs
   Palmtops and Wireless Handhelds
   Internet Appliances and Web-Books

Компоненты Описание : NiMH Battery Pack Charge Controller

DESCRIPTION

The DS2715 is well suited for cost-sensitive charger applications where the Battery is either internal or in a unique Battery pack. It has been optimized for safe reliable charging of 1 to10 NiMH cells in series. The DS2715 has an internal gain block that can be selected as either a comparator or transconductance amplifier for charge current regulation. The DS2715 is configurable as a switched DC charger, a linear current regulator, or a switchmode current source. The DS2715 pre-conditions severely depleted cells are pre-conditioned before entering full charge mode. The DS2715 terminates full charge using the dT/dt technique. It requires an external thermistor for dT/dt detection. Over-temperature, under-temperature, and over-voltage detection prevents charging under unsafe environmental conditions. A user selectable charge timer allows charge rates from 0.15C to 2C. Fast-charge, top-off and charge done modes are included for highly reliable, safe charging of NiMH cells. Discharge mode allows the DS2715 to enter a low power sleep state while the cell pack is being discharged.



FEATURES

■ Charges 1 to 10 NiMH Cells

■ Fast Charges up to a 2C Rate

■ Pre-Charge and Top-Off Charge Modes Help Cell Conditioning

■ Load Detection Allows the DS2715 to Enter Low Power Sleep Mode (Less than 10µA) while the Cell Pack is Discharged

■ dT/dt Charge Termination Eliminates Cell Charge Stress

■ Monitors Voltage, Temperature, and Time for Safety and Secondary Termination

■ Regulates Current through Either Linear Control or Switch-Mode Control

■ LED Outputs Display Charge State

■ Small 16-Pin SO Package

Компоненты Описание : Fast charge ICs for NiCd and NiMH batteries

GENERAL DESCRIPTION

The TEA1103x are fast charge ICs which are able to fast charge NiCd and NiMH batteries.

The main fast charge termination for NiCd and NiMH batteries are ∆T/∆t and peak voltage detection, both of which are well proven techniques. The TEA1103x automatically switches over from ∆T/∆t to peak voltage detection if the thermistor fails or is not present. The ∆T/∆t detection sensitivity is temperature dependent, thus avoiding false charge termination. Three charge states can be distinguished; fast, top-off and trickle.

• Safe and fast charging of Nickel Cadmium (NiCd) and Nickel Metal Hydride (NiMH) batteries

• Pin compatible with the TEA1102x, fast charge ICs for LiIon, SLA, NiCd and NiMH batteries

• Adjustable fast charge current [0.5CA to 5CA nominal (CA = Capacity Amperes)]

• DC top-off and pulsating trickle charge current (NiCd and NiMH)

• Temperature dependent ∆T/∆t Battery full detection

• Automatic switch-over to accurate peak voltage detection (−1⁄4%) if no NTC is applied

• Possibility to use both ∆T/∆t and peak voltage detection as main fast charge termination

• Support of inhibit during all charging states

• Manual refresh with regulated adjustable discharge current (NiCd and NiMH)

• Voltage regulation in the event of no Battery

• Support of Battery voltage based charge indication and buzzer signalling at Battery insertion, end of refresh and at full detection
