The UC3845G-S08-R is a Switching Controllers SOP-8_150mil RoHS manufactured by Unisonic. It is a high performance PWM controller featuring three Pulse-width-modulation (PWM) outputs and a digital error amplifier. It has a wide operating temperature range of -40°C to +125°C and a built-in Undervoltage Lockout (UVLO). It is an RoHS-compliant universal multi-function device capable of providing the control of 3-phase Brushless DC (BLDC) motors, Switched Mode Power Supplies (SMPS), Uninterruptible Power Supply (UPS) systems, and more. The UC3845G-S08-R is designed to reduce the size and cost of the system by combining all the functions of the commonly used devices such as MOSFET drivers, opto-couplers, oscillators, error amplifiers, gate drivers, and more. It is a surface-mount device with a standard SOP-8_150mil package.
