Toshiba Semiconductor and Storage TB62213AFG,C8,EL

Overview

TB62213AFG,C8,EL from Toshiba is a two-phase bipolar stepping motor driver IC fabricated in BiCD silicon monolithic process, delivering 40 V/3.0 A output capability with PWM chopper control and integrated VCC regulator. It supports Full, Half, and 1/4-step excitation modes and operates from a single VM supply, targeting precision motion control in industrial automation and office equipment.

For engineers reviewing the TB62213AFG,C8,EL datasheet, TB62213AFG,C8,EL pinout, TB62213AFG,C8,EL application, or TB62213AFG,C8,EL equivalent, key selection considerations include its 100 kHz chopper frequency, thermal shutdown (150°C), overcurrent protection (≥3.0 A), RS-sense current feedback architecture, and HSOP28 package thermal performance under continuous 2.4 A per phase operation.

Technical Context

The TB62213AFG,C8,EL implements mixed-decay PWM current control using dual H-bridge outputs with external RS-sense resistors and programmable VREF inputs. Its internal oscillator (OSCM) sets chopper frequency via external R/C network (e.g., 3.6 kΩ + 270 pF → 1.6 MHz OSCM → 100 kHz fchop).

It integrates independent protection circuits per phase: overcurrent shutdown (ISD) with 4-cycle masking, thermal shutdown (TSD) at 140–170°C junction temperature, and power-on reset (POR) for VM and VCC. Logic-level inputs (VIH = 2.0–5.5 V, VIL ≤ 0.8 V) interface directly with microcontrollers without level-shifting.

FAQ

What is the maximum continuous output current per phase for TB62213AFG,C8,EL under standard operating conditions?

The TB62213AFG,C8,EL delivers 2.4 A per phase continuously at Ta = 25°C with proper PCB copper area and airflow. Derating applies above 25°C ambient (9.2 mW/°C), and the absolute maximum rating is 3.0 A. Actual sustained current depends on thermal design - the HSOP28 package requires adequate copper pour and optional heatsinking to maintain junction temperature below 150°C in TB62213AFG,C8,EL applications.

How does the TB62213AFG,C8,EL achieve constant-current control without an external current-sense amplifier?

The TB62213AFG,C8,EL integrates internal current-sense comparators referenced to VREF inputs and RS_A/RS_B pins. It measures voltage drop across external sense resistors (e.g., 0.62 Ω) and adjusts PWM duty cycle in real time to maintain IOUT = VREF/5/RRS. This eliminates need for external op-amps or amplifiers - all regulation logic, oscillation, and H-bridge control reside within the TB62213AFG,C8,EL die.

Can TB62213AFG,C8,EL operate from a single 24 V supply, and what internal rails does it generate?

Yes, TB62213AFG,C8,EL operates from a single VM supply (10–38 V typical). Its on-chip VCC regulator generates a stable ~5 V internal supply for logic and control circuits - confirmed by VCC pin monitoring function and POR behavior. No external 5 V rail is needed, simplifying power design and reducing component count in systems using TB62213AFG,C8,EL.

What protection features are built into TB62213AFG,C8,EL, and how do they respond to fault conditions?

TB62213AFG,C8,EL includes thermal shutdown (TSD) at 140–170°C, overcurrent shutdown (ISD) per phase ≥3.0 A, and power-on reset (POR) for VM/VCC. During TSD or ISD, outputs disable and remain latched until STANDBY toggles Low→High or power cycles. These protections act autonomously - no host MCU intervention is required to prevent damage during motor stall or wiring faults in TB62213AFG,C8,EL deployments.

Is TB62213AFG,C8,EL compatible with microcontrollers using 3.3 V logic levels?

Yes, TB62213AFG,C8,EL accepts 3.3 V logic inputs: VIH(min) = 2.0 V and VIH(typ) = 3.3 V per datasheet, with 100–300 mV hysteresis. All control pins (IN_A1/IN_A2/PHASE_A/STANDBY, etc.) interface directly with 3.3 V MCUs without level shifters. The TB62213AFG,C8,EL also tolerates VIN up to 6.0 V, allowing safe operation with 5 V logic if needed.
