MC33887DWB規(guī)格書詳情

The 33887 is a monolithic H-Bridge Power IC with a load current feedback feature making it ideal for closed-loop DC motor control. The IC incorporates internal control logic, charge pump, gate drive, and low RDS(ON) MOSFET output circuitry. The 33887 is able to control inductive loads with continuous DC load currents up to 5.0 A, and with peak current active limiting between 5.2 A and 7.8 A. Output loads can be pulse width modulated (PWM-ed) at frequencies up to 10 kHz. The load current feedback feature provides a proportional (1/375th of the load current) constant-current output suitable for monitoring by a microcontroller’s A/D input. This feature facilitates the design of closed-loop torque/speed control as well as open load detection.

Features

? 5.0 V to 40 V Continuous Operation

? 120 m? RDS(ON) H-Bridge MOSFETs

? TTL/CMOS Compatible Inputs

? PWM Frequencies up to 10 kHz

? Active Current Limiting (Regulation) via Internal Constant OFF-Time

PWM (with Temperature-Dependent Threshold Reduction)

? Output Short Circuit Protection (Short to V+ or Short to GND)

? Undervoltage Shutdown

? Fault Status Reporting

? Sleep Mode with Current Draw ≤50 μA (Inputs Floating or Set to Match

Default Logic States)

? Pb-Free Packaging Designated by Suffix Codes VW and PNB
