MC34932EK

The MC34932EK is a monolithic H-bridge Power IC, designed for any low voltage DC servo motor control application within the current and voltage limits stated in this specification. This device is powered by SMARTMOS technology. Each H-bridge in the 34932 is able to control inductive loads with currents up to 5.0A peak. RMS current capability is subject to the degree of heat sinking provided to the device package. Internal peak current limiting (regulation) is activated at load currents above 6.5A ±1.5A. Output loads can be pulse-width modulated (PWM-ed at frequencies up to 20kHz). A load current feedback feature provides a proportional (0.24% of the load current) current output suitable for monitoring by a microcontroller's A/D input. A status flag output reports under-voltage, over-current and over-temperature fault conditions.

• Automatic thermal back-off
• Real-time load current monitoring
• Design-in simplicity - Integrated H-bridge with charge pump, control, protection and four MOSFETs
• Output short-circuit protection (short to VPWR or GND)
• Over-current limiting (regulation) via internal constant-off-time PWM
• 120mΩ Typical RDS (ON) high efficiency
• Sleep mode with current draw <lt/>20μA
