MC33887
Key Features
- 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
- Output loads can be pulse width modulated (PWM-ed) at frequencies up to 10 kHz
- This feature facilitates the design of closed-loop torque/speed control as well as open load detection
- A Fault Status output terminal reports undervoltage, short circuit, and overtemperature conditions
- Two independent inputs provide polarity control of two half-bridge totem-pole outputs
- Two disable inputs force the H-Bridge outputs to tri-state (exhibit high impedance)
- The 33887 is parametrically specified over a temperature range of -40°C ≤ TA ≤ 125°C and a voltage range of 5.0 V ≤ V+ ≤ 28 V
- The IC can also be operated up to 40 V with derating of the specifications
