TB6528P

The TB6528P universal controller for stepping motor drives is a Bi-CMOS monolithic-type IC for controlling five-phase stepping motors.This IC enables five-phase stepping motor drive units to be configured simply by preparing a pulse oscillator,a switching element and a direct current power source.

Features of the TB6528P are:(1)universal controller;(2)operating supply voltage range is Vcc=4 to 16V;(3)high-output current is 20mA min(source);(4)high noise margin is all input pin are equipped with a schmidt circuit;(5)two types of pulse input is 2 input pin method;(6)power down function is all output is at the "L" level;(7)excitain mode protection function is no fluctions in output even when switching excitation modes;(8)reset function is moves the phase home position across to the excitation status;(9)phase home position monitor;(10)excitation status identification monitor is the controller's operating status is output as a monitor signal;(11)input pulse monitor is the input is output as a monitor signal.

The absolute maximum ratings of the TB6528P can be summarized as:(1):the characteristic is power supply voltage,the symbol is VCC,the rating is -0.5 to 20,the unit is V;(2):the characteristic is output current "H"level,the symbol is IOH,the rating is -30,the unit is mA;(3):the characteristic is output current "L"level,the symbol is IOL,the rating is 2,the unit is mA;(4):the characteristic is output current "H"level (CO,EM,ZO),the symbol is IOH,the rating is -50,the unit is mA;(5):the characteristic is output current "L"level (CO,EM,ZO),the symbol is IOH,the rating is 2,the unit is mA;(6):the characteristic is input voltage,the symbol is VIN,the rating is -0.5 to VCC,the unit is V;(7):the characteristic is input current,the symbol is IIN,the rating is ±1,the unit is mA;(8):the characteristic is power dissipation,the symbol is PD,the rating is 1000,the unit is mW;(9):the characteristic is operating temperature,the symbol is Topr,the rating is -20 to 85,the unit is ;(10):the characteristic is operating temperature,the symbol is Tstg,the rating is -55 to 150,the unit is .
