MC34932EK

NXP Semiconductors Document Number: MC34932 Rev. 4.0, 8/2016 Data Sheet: Technical Data Dual 5.0 A H-Bridge 34932 The 34932 is a monolithic H-Bridge Power IC in a robust thermally enhanced Industrial package. The 34932 has two independent monolithic H-Bridge Power ICs in the same package. They are designed for any low voltage DC servo motor control application within the current and voltage limits stated in this specification. This H-BRIDGE device is powered by SMARTMOS technology. Each H-Bridge in the 34932 is able to control inductive loads with currents up to 5.0 A peak. RMS current capability is subject to the degree of heatsinking provided to the device package. Internal peak current limiting (regulation) is activated at load currents above 6.5 A 1.5 A. Output loads can be pulse-width modulated (PWMed at frequencies up to 20 kHz. A load current feedback feature provides a proportional (0.24% of the load current) current output suitable for monitoring by a microcontrollers A/D input. A status flag output reports undervoltage, overcurrent, and overtemperature fault conditions. Two independent inputs provide polarity control of two half-bridge totem pole EK SUFFIX (PB-FREE) outputs. Two independent disable inputs are provided to force the H-Bridge 98ASA99334D outputs to tri-state (high-impedance off state). 54-PIN SOICW-EP Features Applications 5.0 V to 36 V continuous with 24 V nominal operating voltage (transient DC motor control operation from 5.0 V to 40 V) DC brushed and servo motor driver 235 m maximum R at T = 150 C (each H-Bridge MOSFET) DS(on) J Copiers, printers 3.0 V and 5.0 V TTL/CMOS logic compatible inputs Factory automation Output short-circuit protection (short to VPWR or GND) POS, ATM, vending kiosks Overcurrent limiting (regulation) via internal constant-off-time PWM Robotics Temperature dependant current limit threshold reduction to allow for Security camera control continuous operation without shutdown Ticketing, toll systems All inputs have an internal source/sink to define the default (floating input) states Sleep mode with current draw < 20 A (each half with inputs floating or set to match default logic states) V V PWR DD 34932 SFA VPWRA FBA CCPA OUT1 MOTOR IN1 OUT2 IN2 V PWR PGNDA D1 EN/D2 AGNDA MCU IN3 IN4 D3 VPWRB EN/D4 CCPB FBB OUT3 MOTOR SFB OUT4 V DD PGNDB AGNDB Figure 1.
