Linear Tech Introduces uModule Battery Chargers with Active Current Limit
Linear Technology announced the immediate availability of the LTM8061 and LTM8062, the first devices in a new family of complete system-in-a-package uModule® chargers, supporting an output charge current up to 2A. Both parts provide a complete, efficient 1MHz 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 actively manages the output charge current to maximize the power sourced from a solar cell following Maximum Peak Power Tracking (MPPT) principles. The LTM8061 and LTM8062 operate from an input voltage range of 4.95 to 32V with support for preconditioning, constant-current and constant-voltage mode operation. A 0.5% and 0.75% accurate float voltage respectively ensures maximum energy storage at charge termination set by a minimum current threshold detection or adjustable internal timeout.
