Linear Technology LTM8061 and LTM8062 system-in-a-package uModule charger range
The LTM8061 and LTM8062 are the first devices in a new family of system-in-a-package uModule chargers, and support an output current up to 2 A.
Both devices provide a 1 MHz switching step-down charger solution with as few as just one input capacitor.
The LTM8061 features active input-current management to protect against supply rail droop, while providing maximum charge current to the load.
The LTM8062 manages the output charge current to maximize the power sourced from a solar cell, following maximum peak power tracking principles.
Both operate from an input voltage range of 4.95 to 32 V with support for preconditioning, constant-current and constant-voltage mode operation. A 0.5% and 0.75% accurate float voltage ensures maximum energy storage at charge termination set by a minimum current threshold detection or adjustable internal timeout.
The LTM8061 is specifically targeted at charging Li-Ion or Li-polymer batteries with float voltages of 4.1, 4.2, 8.2 and 8.4 V. An externally adjustable float voltage allows the LTM8062 to support charging of single-and multi-cell Li-Ion, Li-polymer, Lithium iron phosphate (LiFePO4) and sealed lead acid (SLA) batteries up to 14.4 V.
To maintain the battery at full charge, the devices automatically initiate a recharge cycle once the battery voltage drops to 2.5% below the float voltage. Safety features include bad-battery detection and NTC resistor input with fault indicator suitable for use with an LED.
An internal input reverse voltage blocking diode is available to prevent leakage current from the battery when the power source is not present.
