The product can be programmed for float voltages between 3.3V and 14.4V with just two external resistors, operating under a 1MHz fixed frequency, average current mode step-down architecture. A 2A power Schottky diode is integrated within the μModule for reverse input voltage protection. A wide input range allows the operation to full charge from an input voltage up to 32V. A precision threshold on the RUN pin allows the implementation of a UVLO feature by using a simple resistor network. The charger can also be put into a low current shutdown mode, in which the input supply bias is reduced to only 15μA. The LTM8062 employs an input voltage regulation loop, which reduces charge current if a monitored input volt- age falls below a programmed level. When the LTM8062 is powered by a solar panel, the input regulation loop is used to maintain the panel at peak output power. The LTM8062 automatically enters a battery precondition mode if the sensed battery voltage is very low. In this mode, the charge current is reduced to 300mA. Once the bat- tery voltage climbs above the internally set precondition threshold (2.3V at the ADJ pin), the μModule automati- cally increases the maximum charge current to the full programmed value. The LTM8062 can use a charge current based C/10 termina- tion scheme, which ends a charge cycle when the battery charge current falls to one-tenth the programmed charge current. The LTM8062 also contains an internal charge cycle control timer, for timer-based termination. When using the internal timer, the charge cycle can continue beyond the C/10 level to top-off the battery. The charge cycle terminates when the programmed time elapses, about three hours for a 0.68μF timer capacitor. The CHRG status pin continues to signal charging at a C/10 or greater rate, regardless of OPERATION |
