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 current per winding at 4.5–10 V motor supply voltage. It supports half-step, full-step, and microstepping modes via TTL-compatible logic inputs (I0/I1, PHASE), features internal PWM current control with external reference voltage (VREF) adjustment, and integrates thermal shutdown and cross-conduction protection. It is used in precision open-loop motion control for industrial automation actuators.

For engineers reviewing the L6219R013TR datasheet, L6219R013TR pinout, L6219R013TR application, or L6219R013TR equivalent, key selection criteria include verified bipolar H-bridge topology, 500 mA per-phase current capability with ±1 A peak, SO-24 package thermal resistance (R_thj-case = 18 °C/W), and compatibility with LS-TTL/microprocessor step/direction interfaces.

Technical Context

The L6219R013TR implements a dual H-bridge power stage using Darlington source drivers and saturated sink drivers, each with integrated clamp diodes for current recirculation. Its PWM-based current regulation uses an external sense resistor (RS) and comparator feedback loop referenced to VREF, with off-time controlled by an RC network (RT/CT) setting t_off = 1.1·R_TC_T.

Logic-level inputs (I0/I1 per bridge) select one of four current levels (0%, 33%, 67%, or 100% of I_MAX), while the PHASE input determines current direction with Schmitt-trigger noise immunity and built-in delay to prevent shoot-through. Thermal shutdown activates at T_J = 170 °C, disabling outputs until junction temperature falls below hysteresis threshold.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TB6600HG	Higher 4.5 A peak current, external MOSFET gate drivers, no integrated sense resistors or PWM oscillator	Requires external current-sense amplifier, gate drivers, and PWM controller; suited for high-torque NEMA 23+ motors	Select when >1 A per phase is required and board space allows supporting components

FAQ

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

The L6219R013TR supports a continuous motor supply voltage range of 4.5 V to 10 V. Absolute maximum rating is 30 V, but operation above 10 V risks exceeding safe power dissipation limits and triggering thermal shutdown under load. The device is explicitly designed for unstabilized 5 V or 9 V rails, and Figure 6 in the datasheet confirms 500 mA output current is guaranteed only up to 10 V at T_J ≤ 125 °C.

How does the PHASE input control current direction in the motor winding?

A high logic level on PHASEA causes current to flow from OUTA to OUTB through winding A; a low level reverses direction (OUTB to OUTA). The input passes through a Schmitt trigger for noise immunity and a hardware delay circuit that enforces minimum dead time between bridge state transitions, preventing shoot-through during direction changes. This behavior is confirmed in Section 3.2 and Figure 4 of the datasheet.

Can the L6219R013TR drive unipolar stepper motors?

No. The L6219R013TR is designed exclusively for bipolar stepper motors with center-tapped windings omitted. Its dual full-bridge topology requires four-wire bipolar connections (OUTA, OUTB, SENSEA, SENSEB) and cannot replicate the unipolar switching pattern needed for five- or six-wire motors. Attempting unipolar use would result in incorrect current paths and potential device damage.

What is the purpose of the RC pin and how is its timing calculated?

The RC pin connects an external R_T/C_T network that sets the PWM off-time (t_off) during current regulation. The monostable pulse generator produces t_off = 1.1·R_TC_T, controlling how long the bridge remains off to allow winding current to decay. Typical values are R_T = 56 kΩ and C_T = 820 pF, yielding t_off ≈ 50 μs - a value validated in Table 5 and Section 3.4 for stable 500 mA regulation.
