TP4056 vs TP4057

Differences between TP4056 VS TP4057 in Pin Configuration and Application Circuits:

TP4056 pinout VS TP4057 pinout

Comparison Item	TP4056 (SOP-8 Package)	TP4057 (SOT23-6 Package)
Chip Pins	8-pin Package ① TEMP (Temperature sensing input) ② PROG (Charge current setting) ③ GND (Ground) ④ VCC (Power input) ⑤ BAT (Battery positive terminal) ⑥ STDBY (Charge complete indicator) ⑦ CHRG (Charging status indicator) ⑧ CE (Chip enable control)	6-pin Package ① CHRG (Charging status indicator) ② GND (Ground) ③ BAT (Battery positive terminal) ④ VCC (Power input) ⑤ STDBY (Charge complete indicator) ⑥ PROG (Charge current setting)
Pin Differences Summary	Includes additional TEMP pin for temperature sensing. CE pin available for external control to enable/disable the chip.	No TEMP pin for temperature sensing. No CE pin; chip is always enabled.
Application Circuit Differences	More complex; supports NTC thermistor (connected to TEMP pin) for battery temperature monitoring. Includes additional enable/disable functionality (via CE pin).	Simpler; no temperature monitoring function, ideal for compact and space-constrained designs.
Maximum Charge Current	Up to 1A	Recommended maximum of 500mA
Charge Current Setting Formula	我_CHG = 1200 / R_PROG	我_CHG = 1000 / R_PROG
Typical Rprog Selection	1.2kΩ resistor for 1A charge current	2kΩ resistor for approximately 500mA charge current

TP4056 VS TP4057 peripheral circuits, specific pin connections, and functions of each external component:

TP4056 Circuit VS TP4057 Circuit

Component	TP4056 Peripheral Circuit (Left Diagram)	TP4057 Peripheral Circuit (Right Diagram)
Input Current-Limiting Resistor	RL1 = 0.4Ω, connected to VCC (Pin 4) Limits input surge current to protect the chip from potential damage.	Not Present (5V input directly to VCC, Pin 4)
Input Filter Capacitor	C1 = 10μF, connected between VCC (Pin 4) and GND (Pin 3) Reduces ripple noise and stabilizes input voltage.	1μF, connected between VCC (Pin 4) and GND (Pin 2) Basic noise filtering for compact designs.
Output Filter Capacitor	C2 = 10μF, connected between BAT (Pin 5) and GND (Pin 3) Ensures stable battery voltage and reduces output ripple.	10μF, connected between BAT (Pin 3) and GND (Pin 2) Same function: stabilizes battery voltage during charging.
Charging Status LEDs and Resistors	Two LEDs: – D1 with RL2=1kΩ resistor, connected to CHRG (Pin 7): indicates charging status. – D2 with RL3=1kΩ resistor, connected to STDBY (Pin 6): indicates charging completed or standby mode.	Single LED with 1kΩ resistor connected to CHRG (Pin 1) Simplified indicator for charging status only.
Charge Current Setting Resistor (Rprog)	Rprog resistor connected between PROG (Pin 2) and GND (Pin 3) Determines charging current, e.g., 1.2kΩ sets approx. 1A.	Rprog = 1.66kΩ, connected between PROG (Pin 6) and GND (Pin 2) Sets charging current around 600mA.
Temperature Sensing Resistor (NTC)	RL4 (10kΩ or NTC thermistor) connected between TEMP (Pin 1) and GND (Pin 3) Monitors battery temperature for enhanced safety during charging.	No Temperature Sensing Capability
Chip Enable Control (CE Pin)	CE (Pin 8): external control signal Allows enabling or disabling the chip.	No Enable Control Pin Chip always enabled by default.
