Product details

Overview

L6219R013TR from STMicroelectronics is a bipolar stepper motor driver IC with dual full-bridge output stage, capable of delivering up to 500 mA continuous per winding at 4.5–10 V motor supply, featuring internal PWM current control, thermal shutdown, and built-in recirculation diodes for driving bipolar stepper motors in microstepping, half-step, and full-step modes.

For engineers reviewing the L6219R013TR datasheet, L6219R013TR pinout, L6219R013TR application, or L6219R013TR equivalent, this device is selected for precise open-loop motion control in compact industrial actuators, printer mechanisms, and embedded positioning systems where unstabilized motor supply voltage and integrated current sensing are required.

Technical Context

The L6219R013TR implements a switch-mode current regulation architecture using external sense resistors and internal comparators with selectable reference thresholds via two logic inputs (I0/I1), enabling three discrete current levels (0%, 33%, 67%, 100% of I_MAX). Each H-bridge includes Darlington source drivers and saturated sink drivers with clamping diodes for bidirectional winding control.

Phase input determines current direction per bridge with Schmitt-trigger noise immunity and internal delay to prevent shoot-through; RC network on pin 12 sets off-time (t_OFF = 1.1·R_TC_T) for PWM decay control. Thermal shutdown activates at T_J = 170 °C, disabling outputs until junction temperature falls below hysteresis threshold.

Key Specifications

Parameter	Value and Actual Design Meaning
Output current (continuous)	±500 mA per winding - supports NEMA 8–11 stepper motors with 0.3–0.6 A/phase rating
Motor supply range	4.5 V to 10 V - operates directly from unregulated 5 V or 9 V rails without LDO pre-regulation
Logic supply voltage	4.75 V to 5.25 V - compatible with standard 5 V TTL/CMOS microcontroller interfaces
Output saturation voltage	0.3–1.6 V (sink/source, 300–500 mA) - limits conduction loss to ≤0.8 W per bridge at max current
Thermal shutdown threshold	170 °C junction temperature - protects die during sustained stall or high ambient conditions
Reference voltage range	1.5 V to 2.0 V - sets current limit threshold in conjunction with external sense resistor (e.g., 0.5 Ω → 2 A/V)
Input logic compatibility	TTL/CMOS - accepts 0.8 V low / 2.4 V high thresholds with <1 μA leakage

Equivalent & Alternatives

The following parts are listed as comparable options for similar bipolar stepper motor driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DRV8811PWPR	Higher current (1.5 A), integrated current DAC, SPI interface instead of analog VREF	Requires microcontroller with SPI; supports dynamic current adjustment mid-motion	Select when programmable current profiling or higher torque is needed; not drop-in due to interface and pinout differences
TB6560AHQ	Higher voltage (45 V), microstepping up to 1/8-step, no internal diodes - requires external flyback diodes	Suited for larger NEMA 17+ motors; adds complexity with external protection components	Select for wider supply range and finer microstepping; avoid if board space or BOM count is constrained

Compared with DRV8811PWPR and TB6560AHQ, the L6219R013TR offers simpler analog current setting, lower component count, and proven reliability in cost-sensitive, space-constrained 5 V systems - ideal where fixed-torque, TTL-driven operation suffices.

FAQ

What is the maximum allowable motor supply voltage for continuous operation?

The L6219R013TR supports continuous operation up to 10 V on the VS pin, with absolute maximum rating of 30 V for transient conditions only. Exceeding 10 V risks excessive power dissipation in the output transistors, especially at 500 mA load, and may trigger thermal shutdown prematurely. Operation above 10 V requires derating and careful thermal design.

Can the L6219R013TR drive unipolar stepper motors?

No - the L6219R013TR is designed exclusively for bipolar stepper motors with center-tapped windings. Its dual full-bridge topology requires four-wire connection (OUTA, OUTB per winding) and cannot interface with the five- or six-wire configurations typical of unipolar steppers. Attempting unipolar use results in incorrect current paths and potential device damage.

How is current limit set without a DAC or digital interface?

Current limit is set by applying a DC reference voltage (1.5–2.0 V) to the VREF pin and selecting one of four gain states via I0/I1 logic inputs. The peak current equals VREF divided by (10 × Rs), where Rs is the external sense resistor value. This analog method avoids digital communication overhead while maintaining ±5% regulation accuracy over temperature.

Is external flyback diode placement required?

No - the L6219R013TR integrates eight clamp diodes (two per transistor) within each H-bridge, providing complete recirculation paths for inductive kickback during PWM decay. External diodes are unnecessary and would interfere with internal current sensing; only local 100 nF VS-to-GND decoupling and short Rs ground traces are required per datasheet layout guidelines.
