Interfaces 
Analogue I/O Ports, AIO 
B6Z-400 has 1 general-purpose analogue interface pin, AIO[0]. Typically, this connects to a thermistor for 
battery pack temperature measurements during charge control. 
LED Drivers 
B6Z-400 includes a 3-pad synchronised PWM LED driver for driving RGB LEDs for producing a wide range 
of colours. All LEDs are controlled by firmware. 
The terminals are open-drain outputs, so the LED must be connected from a positive supply rail to the pad in series 
with a current-limiting resistor. 
Figure 2.1: LED Equivalent Circuit 
From Figure 2.1 it is possible to derive Equation 2.1 to calculate ILED. If a known value of current is required through 
the LED to give a specific luminous intensity, then the value of RLED is calculated. 
Equation 2.1: LED Current 
For the LED pads to act as resistance, the external series resistor, RLED, needs to be such that the voltage drop 
across it, VR, keeps VPAD below 0.5V. Equation 2.2 also applies. 
VDD = VF + VR + VPAD 
    Equation 2.2: LED PAD Voltage 
Note: 
The LED current adds to the overall current. Conservative LED selection extends battery life. 
Reset, RST# 
B6Z-400 is reset from several sources: 
■ RST# pin 
■ Power-on reset 
■  USB charger attach reset 

■  Software configured watchdog timer 
The RST# pin is an active low reset and is internally filtered using the internal low frequency clock oscillator. Rayson 
recommends applying RST# for a period >5ms. 
At reset the digital I/O pins are set to inputs for bidirectional pins and outputs are set to tristate.
