The Toshiba 1-hall sine-wave PWM driver is for 3-phase brushless DC motors. DMOS is used in output stages, realizing low-on-resistance of 0.2 Ω (total of high and low sides). A non-volatile memory (NVM) and a closed loop speed control function are incorporated.
Built-in closed loop speed control, configurable speed curve Low on resistance: RDS(H+L)=0.2 Ω (typ.) Driving current: 3.5 A max (peak) Operating voltage range: 4.5 to 16 V Serial interface Standby mode Soft start Built-in protection circuits: Thermal shutdown (TSD), Under voltage lockout (UVLO), Over voltage protection (OVP), Under voltage protection for charge pump, Over current protection (ISD), Output current limit protection (OCP), and Lock detection protection
For products that are Customized and under Non-cancellable & Non-returnable, Sales & Conditions apply.
