PS2 Power Management System
The PS2 Power Management System is an all in one custom power solution for PS2 portables. It allows for seamless charge & play along with built-in battery protection. Each board comes fully assembled, programmed, and fully ready to be installed in your project. The PS2 Power Management System also boasts several must-have features for a fully integrated power solution including:
- Seamless charge & play (play your portable while it's charging) and battery protection
- Built-in regulators (1.25v, 1.8v, 2.5v, 3.3V and a boost for 5V)
- Shipping Mode: Permanently powers off the unit until a charger is plugged in to prevent accidental powering on during travel/shipping
- RGB LED based interface with 4 modes:
- LED off
- RGB fade (cycles through colors)
- Battery monitor (displays colors based on charge level)
- Shipping mode
WARNING: When batteries are wired up to the system, there is voltage flowing throughout the board EVEN WHEN POWERED OFF! Be sure to disconnect the B+ line BEFORE soldering to the board!
The pinout for the PS2 Power Management System is as follows:
R - Wire to PS2 Reset for autobooting the PS2 when the regulators are powered on
Btn - Power button (tact switch wired to GND for ON/OFF)
T-, T+ - Thermistor for thermal protection. Cuts off ~75C (Thermistor included)
R-, B-, G- - Wire to the common anode RGB led, Anode can be wired to a source voltage like 3.3v
CHRG - This is the DC voltage source charger input. Recommended to use 12V DC. Cannot exceed 14V! The default code is set to charge 3.072A which is ideal for a 1S2P 18650 battery configuration. Please make sure to check the specifications of the battery against the charging settings of the system before use.
B+ - Battery positive connection
