What are the key features of LTC4079EDD#TRPBF?
- 60V maximum input voltage enabling direct charging from solar panels and high-voltage adapters without pre-regulation
- 250mA maximum charge current with adjustable termination threshold for flexible cell chemistry support
- Ultra-low quiescent current minimizing battery drain during standby for always-on portable devices
- Single-channel linear charger architecture simplifying thermal management and PCB layout
- 10-pin DFN package with exposed thermal pad for efficient heat dissipation in compact charger designs
What is LTC4079EDD#TRPBF used for?
LTC4079EDD#TRPBF is designed for solar-powered IoT sensor nodes, remote monitoring equipment, and industrial field devices that charge single-cell lithium batteries directly from high-voltage sources up to 60V. Its adjustable threshold and low quiescent current make it ideal for energy-harvesting applications where charging current is intermittent and standby power must be minimized. Wearable devices, medical monitoring patches, and backup battery circuits in industrial controllers also benefit from its compact DFN package and simple single-resistor configuration.

Frequently Asked Questions
What input voltage range does LTC4079EDD#TRPBF support, and why does this matter for solar charging?
LTC4079EDD#TRPBF accepts input voltages up to 60V, which is high enough to connect directly to small solar panels without an intermediate DC-DC converter. A typical 12V or 24V solar panel output with open-circuit voltage spikes fits within this 60V limit, simplifying the power path and reducing BOM cost for off-grid sensor and remote monitoring designs with a 250mA maximum charge current.
How does LTC4079EDD#TRPBF compare to LTC4069 for a 12V industrial battery charger application?
LTC4079EDD#TRPBF handles up to 60V input versus LTC4069's 6V maximum, making it the correct choice when the charging source is a 12V industrial bus with transients that could reach 40V to 60V. Both deliver up to 250mA charge current with a linear architecture, but LTC4079EDD#TRPBF's wide input range eliminates the need for a separate voltage clamp or pre-regulator in 12V to 48V industrial system charger designs.
What package does LTC4079EDD#TRPBF use, and how does it handle thermal dissipation at 250mA charge current?
LTC4079EDD#TRPBF is housed in a 10-pin DFN package with an exposed thermal pad on the bottom, which conducts heat directly to the PCB copper pour. At 250mA charge current with a large input-to-output voltage differential typical of solar applications, junction temperature must be managed through the exposed pad and copper area; the thermal resistance from junction to board is approximately 43°C/W, limiting maximum ambient temperature at full load.
