MAX1926ETC+

The MAX1926ETC+ is a switch-mode, 1-cell Li+ charger in 12 pin TQFN package. This device use an external PMOS pass element in step-down configuration. Charge current is programmable and an external capacitor sets the maximum charge time. It includes automatic input power detection (active-low ACON output), logic-controlled enable and temperature monitoring with an external thermistor. MAX1926 charges inputs between 4.25V and 12V and features two precondition levels to restore near-dead cells.

• ±0.75% battery regulation voltage
• Set charge current with one resistor
• Automatic input power sense
• LED (or logic-out) charge status and fault indicator
• Programmable safety timer
• Autorestart at cell = 4V
• Thermistor monitor input
• Operating temperature range from -40°C to 85°C
