TB62213AHQ,8

Overview

The TB62213AHQ,8 is a bipolar stepper motor driver IC manufactured by Toshiba Semiconductor and Storage. It features a 25-HZIP package with through-hole mounting. The device supports a load voltage range of 10 V to 38 V and delivers an output current of 1.8 A. It operates on a 5 V supply voltage (4.75 V to 5.25 V) with a quiescent current of 2.5 mA. The component handles a power dissipation of 3.5 W and functions within a temperature range of -20°C to +85°C. It includes four output channels and supports stepping resolutions of 1, 1/2, and 1/4.

Feature Summary

• Integrates control logic and power MOSFETs for full bipolar stepper motor driving
• Supports multiple stepping resolutions including full, half, and quarter steps
• Includes built-in protection mechanisms against overcurrent and thermal overload

Applications

• Bipolar stepper motor control in industrial automation equipment
• Motion control systems requiring precise positioning
• Office automation devices such as printers and scanners

Procurement Notes

Verify the specific suffix 'HQ,8' to confirm the HZIP-25 through-hole package variant. Ensure the application design accommodates the 3.5 W power dissipation requirement, potentially necessitating adequate thermal management solutions. Confirm that the 1.8 A continuous output current aligns with the motor specifications. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a through-hole solution is required for bipolar stepper motors. Compare the 1.8 A output capability against the motor's rated current requirements. Consider the 25-HZIP package dimensions for PCB layout constraints. Evaluate the thermal performance at the maximum operating temperature of 85°C to ensure reliability under load conditions.

Part Context

This part belongs to the TB62213 family of stepper motor drivers from Toshiba. It shares functional similarities with other variants like the TB62213AFG but differs in packaging and mounting style. The AHQ,8 designation specifically identifies the through-hole HZIP-25 configuration, distinguishing it from surface-mount alternatives within the same product line.
