8 / 12 page Analog Integrated Circuit Device Data 8 Freescale Semiconductor 17533 FUNCTIONAL DESCRIPTION INTRODUCTION FUNCTIONAL DESCRIPTION INTRODUCTION The 17533 is a monolithic dual H-Bridge ideal for portable electronic applications to control bipolar stepper motors and brush DC motors such as those found in camera len assemblies, camera shutters, optical disk drives, etc. The 17533 operates from 2.0 V to 6.8 V, with independent control of each H-Bridge via parallel MCU interface (3.0 V- and 5.0 V-compatible I/O). The device features built-in shoot- through current protection and undervoltage shutdown. The 17533 has four operating modes: Forward, Reverse, Brake, and Tri-Stated (High Impedance). The MOSFETs comprising the output bridge have a total source + sink RDS(ON) ≤ 1.2 Ω. The 17533 can simultaneously drive two brush DC motors or, as shown in the simplified application diagram on page 1, one bipolar stepper motor. The drivers are designed to be PWM’ed at frequencies up to 200 kHz. FUNCTIONAL PIN DESCRIPTION LOGIC SUPPLY (VDD) The VDD pin carries the logic supply voltage and current into the logic sections of the IC. VDD has an undervoltage threshold. If the supply voltage drops below the undervoltage threshold, the output power stage switches to a tri-state condition. When the supply voltage returns to a level that is above the threshold, the power stage automatically resumes normal operation according to the established condition of the input control pins. LOGIC INPUT CONTROL (IN1A, IN1B, IN2A, AND IN2B) These logic input pins control each H-Bridge output (e.g., IN1A logic HIGH = OUT1A HIGH, etc.). However, if all inputs are taken HIGH, the outputs bridges are both tri-stated (refer to Table 5, Truth Table, page 7). OUTPUT ENABLE (OE) The OE pin is a LOW = TRUE enable input. When OE = HIGH, all H-Bridge outputs (OUT1A, OUT1B, OUT2A, and OUT2B) are tri-stated (high-impedance), regardless of logic inputs (IN1A, IN1B, IN2A, and IN2B) states. OUTPUT A AND B OF H-BRIDGE CHANNEL 1 AND 2 (OUT1A, OUT1B, OUT2A, AND OUT2B) These pins provide connection to the outputs of each of the internal H-Bridges (see Figure 2, 17533 Simplified Internal Block Diagram, page 2). MOTOR DRIVE POWER SUPPLY (VM1 AND VM2) The VM pins carry the main supply voltage and current into the power sections of the IC. This supply then becomes controlled and/or modulated by the IC as it delivers the power to the loads attached between the output pins. All VM pins must be connected together on the printed circuit board. GATE DRIVER CIRCUIT VOLTAGE INPUT (VG) The VG pin is the input pin for the gate drive voltage. POWER GROUND (PGND) Power ground pins. They must be tied together on the PCB. LOGIC GROUND (LGND) Logic ground pin. |
