The setting of channel current for SiLM4228x (x=0, 1, 2, 3) is as follows:
1. Divide 1.5V by the resistance of IRx (x=1, 2, 3) pins to obtain a current;
2. Multiply the current obtained above by 960 times to obtain the corresponding channel current.
SiLM4228x (x=0, 1, 2, 3) has identical parameters except for the Open diagnostic enable threshold.
It is recommended to connect to the VEE2 pin. During normal use, connect to the OUT pin. The Clamp function triggers clamping by adjusting the voltage of the clamp pin itself. When the clamp voltage is below 2V, the Vclamp is pulled down to VEE2.
It is recommended to add a resistor and a capacitor (2.2nF is recommended) to maintain the stability of the DT voltage, so as to ensure that the DT time from channel A to channel B and from channel B to channel A is equal.
It is recommended to short connect the VSS pin to COM, with a pressure difference of no more than 5V.
It is recommended to connect the VLED pin to the VEE (not VE).
Two zero drift operational amplifiers are integrated in SLM8834, which can be used for analog PID control. However, SLM8833 does not integrate these two operational amplifiers and can only be controlled using digital PID.
