Specifications and information herein are subject to change without notice. © Motorola, Inc. 2004 Document order number: MC34920 Rev 1.0, 01/2004 34920 Advance Information Simplified Application Diagram + + DC MOTOR DC MOTOR 34920 MCU VVB+ VV2 VV1 DR1A DR2A DR1B DR2B CP1 CP2 DR2PWM SDI DR1PWM SCLK RESET CS Vb VVB+ + GND ORDERING INFORMATION Device Temperature Range (TA) Package MC34920EI/FN/R2 0°C to 70°C 44 PLCC 2.8 Ω (Typ) Quad H-Bridge Motor Driver The 34920 is a multifunctional analog ASIC. The 34920 integrates two circuits, four H-bridge drivers, a reset circuit in a single IC, and two DC/DC switching voltage regulators. Input voltage is 21 V to 42 V DC. Each motor of the two driver blocks can be configured as either a DC motor driver with pulse width modulation (PWM)-control or a single bipolar step motor driver. In step motor mode, both drivers are capable of being operated in the quarter step mode. In DC motor mode, both bridges in a driver are in parallel, providing 2.4 A of drive current. In step motor mode, each bridge in a driver drives one phase. Each phase is driven with a bipolar current mode drive. Features • Individual Thermal Limit Protection • User-Selectable Motors: 2 DC Motors (2.4 A/Motor), 2 Step Motors (W1-2 Phase Control), 1 DC Motor and 1 Step Motor • 2 Buck Regulators (Switching @ 200 kHz) •VV2 Output Voltage Is Programmable to 10 V to 15 V DC (Externally Set) • Low-Voltage Detection Reset (VV1 and VVB+) • Pb-Free Packaging Designated by Suffix Code EI 2.8 Ω (TYP) QUAD H-BRIDGE MOTOR DRIVER EI (Pb-FREE) SUFFIX FN SUFFIX CASE 777 44-TERMINAL PLCC 34920 Simplified Application Diagram Freescale Semiconductor, Inc.
