STMicroelectronics L6207D013TR

Overview

L6207D013TR from STMicroelectronics is a DMOS dual full-bridge motor driver IC with integrated constant t_OFF PWM current controllers, designed for bipolar stepper and dual DC motor control. It operates from 8–52 V, delivers 5.6 A peak (2.8 A DC) per bridge, features 0.3 Ω typical R_DS(ON) at 25 °C, supports up to 100 kHz switching, and includes non-dissipative overcurrent protection and thermal shutdown.

For engineers reviewing the L6207D013TR datasheet, L6207D013TR pinout, L6207D013TR application, or L6207D013TR equivalent, key selection considerations include its dual independent PWM current regulation, slow-decay synchronous rectification, cross-conduction protection, bootstrap gate drive architecture, and PowerSO36 package thermal performance.

Technical Context

The L6207D013TR integrates two fully isolated DMOS full bridges in BCD technology, each with high-side and low-side N-channel MOSFETs and intrinsic fast freewheeling diodes. Its constant t_OFF PWM controllers use external RC networks on RCA/RCB pins to set recirculation time (13–61 µs), while internal blanking (1 µs) suppresses sense-current spikes during diode reverse recovery.

Logic inputs (IN1A/IN2A/IN1B/IN2B) are TTL/CMOS-compatible with 1.8 V turn-on and 1.3 V turn-off thresholds; ENA/ENB pins serve dual roles-bridge enable and open-drain fault reporting-with recommended 100 kΩ pull-up resistors. The charge pump (VCP output, 0.6–1 MHz) generates VBOOT for high-side gate drive, requiring external 220 nF boot capacitor and 10 nF pump capacitor.

FAQ

What is the maximum allowable supply voltage for continuous operation?

The L6207D013TR has a recommended operating supply voltage range of 8–52 V, with an absolute maximum rating of 60 V. Continuous operation above 52 V risks exceeding safe operating area limits and triggering undervoltage lockout or thermal shutdown. For 48 V nominal systems, derating is not required, but transient suppression (e.g., TVS diode) is advised for load-dump events.

How does the non-dissipative overcurrent protection work without a sense resistor?

The L6207D013TR embeds a precision current mirror on each high-side DMOS transistor that delivers a scaled replica (typically 1/2000) of the output current to an internal comparator. When this replica exceeds the internal reference (~5.6 A × 1/2000), the EN pin is actively pulled low. This eliminates the need for external shunt resistors and their associated power loss and PCB footprint.

Can the L6207D013TR drive unipolar stepper motors?

No - the L6207D013TR is designed exclusively for dual full-bridge topologies and cannot directly drive unipolar steppers, which require five-wire configurations with center-tapped windings and single-ended switching. It supports only bipolar (four-wire) stepper motors and dual independent DC motors via its two fully isolated H-bridges.

What thermal interface materials are recommended for the PowerSO36 slug?

For optimal thermal performance, ST recommends soldering the exposed slug (pins 1, 18, 19, 36) directly to a minimum 6 cm² copper pour on the PCB's bottom layer, using standard lead-free reflow profile. Thermal vias (≥16, 0.3 mm diameter, filled or capped) should connect the slug to internal ground planes. No additional TIM (e.g., grease or pad) is required or recommended - mechanical clamping or adhesive is unnecessary and may impair solder joint reliability.
