Product Summary

The IXMS150PSI is a high performance monolithic 2-channel PWM controller. Implemented in CMOS, the low power IXMS150PSI precisely controls the current in each of two separate power H-bridge drivers using unique sampling and signal processing techniques. The applications of the IXMS150PSI are (1)Full, half quarter, or microstepping 2-phase step motor position; (2)controller; (3)Dual DC servo motor torque controller; (4)Solenoid actuator force controller; (5)General 2-channel current-commanded PWM control.

Parametrics

IXMS150PSI absolute maximum ratings: (1)VDD Supply voltage: -0.3 to 15 V; (2)Operating range: 10.8 to 13.2 V; (3)Common-mode-range: -15 to 15 V; (4)Differential Input voltage: ±30 V; (5)VIN Input voltage: -15 to 15 V; (6)VO Output voltage: -0.3 to VDD+0.3 V; (7)PD Maximum power dissipation: 500 mW; (8)TA Ambient temperature range: -40 to 85℃; (9)Tstg Storage temperature range: -55 to 125℃.

Features

IXMS150PSI features: (1)Two complete, synchronous PWMs; (2)Command input range ±2.0 V full scale; (3)±0.625 V full scale current feedback signal; (4)1% gain matching between channels without external trim; (5)1.6% gain linearity; (6)Feedforward to compensate for motor supply variations; (7)Only one sense resistor per H-bridge needed; (8)Onboard two level current limiting; (9)Undervoltage lockout assures proper behavior on power up and power down; (10)Enable input for external over temperature or fault circuit input; (11)Duty cycles limited for AC coupled gate drive; (12)Wide range of built in dead time.; (13)On board negative power supply generator; (14)Single +12 V supply operation; (15)24-pin DIP package.
