MC34932SEK数据手册恩XP中文资料规格书

描述 Description

The NXP® MC34932 consists of two independent, monolithic, thermally efficient 36V/5A H-Bridge DC motor drivers in the same package.
Features real-time load current monitoring and automatic thermal back-off ensuring high availability operation in demanding high-current, high-temperature industrial applications
Designed primarily for DC brushed and DC servo motor driver applications within the current and voltage limits stated in this specification
Powered by SMARTMOS® technology
Processor Expert® component for medium voltage H-Bridge products enables rapid embedded application development.

特性 Features

• Best thermal efficiency: eSOIC package delivers 2X lower thermal impedance, saving board space and simplifying design
• Automatic thermal back-off: Temperature regulated, peak current limiting ensures continuous high availability operation
• Real-time load current monitoring: Analog feedback current mirror feature used for motor control or load protection
• Design-in simplicity:Integrated H-Bridge with charge pump, control, protection and four MOSFETs
• High efficiency: 120 mΩ typical RDS(ON)
• 5.0V to 36V continuous operation, 42V transient
• Dual H-Bridge with operation up to 5A on each channel covering a wide range of applications
• 3 & 5 V TTL/CMOS compatible
• Status flag output reports under-voltage, over-current, and over-temperature fault conditions
• Output short-circuit protection (short to VPWR or GND)
• Sleep mode with current draw < 20μA (each half with inputs floating or set to match default logic states)
