Main component
TP4056 Charge Management chip
TP4056 is a commonly used single lithium battery constant current/constant voltage linear charge management chip. The charging current can be set via an external resistor. The specific formula is: Charging current (mA) = 1000 / Rprog (kΩ). For example, if a 1.2kω resistor is used, the charging current is 1000mA / 1.2 = 833mA.
ME4055-N Charge Management chip
-ME4055-N is a constant current charge management chip with a maximum charge current of 800mA. The charging current can be set by connecting an external resistor RPROG to the ground. The charging current formula is: I = 1270 * VPROG/RPROG (where VPROG is the voltage of the PROG pin and RPROG is the resistance value of the PROG pin to the ground).
ASC8511 Charge Management ch
- ASC8511 is a switching, synchronous rectifier single lithium battery charge management chip with a maximum charging current of 2.5A. The constant current charging current ranges from 200mA to 2500mA and is set by the accuracy of the voltage drop on the galvanometer resistor RSNS.
SUM4056B Charge Management Chip
- SUM4056B is a linear charge management chip with charging current up to 1A and can be configured with off-chip resistors. The charging current formula is: IBAT = 1000 / RIREF, where IREF is the resistance value of IREF pin to ground.
DC CHARGING PIlE SERIES
DC charging pile is an efficient charging facility for electric vehicles, which uses direct current (DC) to directly charge the vehicle battery, significantly reducing the charging time. Compared with traditional AC charging piles, DC charging piles are able to provide higher power output and can usually charge an EV to 80% of its capacity in 30 minutes, providing users with a convenient charging experience.
