HPD322 two-phase stepper motor driver is a cost-effective subdivision driver designed based on PI flow control algorithm. It has excellent performance, high speed and large torque output, low noise, low vibration and low heat.
The operating current and subdivision can be selected through the dial switch. There are 16 subdivisions and 16 currents to choose from. It has overvoltage, undervoltage, phase current and total current overcurrent protection. Its input and output control signals are all photoelectric. isolation.
Signal input: single-ended, pulse + direction and double pulse;
Built-in micro-subdivision; the maximum power supply can reach DC36V; the current is easy to set, 16 levels are optional, the output current peak can reach 2.2A; the current is halved after 1S of inactivity
Optically isolated differential signal input, the maximum input pulse frequency is 300KHz;
The pulse, direction and enable terminals all have constant current input functions and can be directly connected to the input signal without adding an external series resistor for voltage reduction and current limiting protection.
High reliability: using multi-layer boards and surface mount sealing, leaving sufficient margin for power devices
Polymer lithium-ion battery 7.4V 1500 mAh, built-in power management chip to avoid overcharging, protect the battery and extend battery life.
Bluetooth SOC solution and Bluetooth link compatibility are better and more stable.
Bluetooth mode and protocol: Bluetooth 4.0 dual-mode Bluetooth (BR/EDR+BLE), 55 meters of open space.
Charging port: TYPE-C interface, which is common with mobile phone charging cables to prevent the traditional miniUSB port cable from being lost and unable to charge.
Rubber stopper protection design to prevent water and dust from entering.
