As a frequently chosen device among engineers, the L6207PD013TR series stands out for its flexibility in automotive, industrial automation, and robotics motor drive applications.

Main Attributes and Innovations of the L6207PD013TR Series

At the core of the L6207PD013TR is its DMOS dual full-bridge architecture, capable of handling peak output currents up to 5.6A (2.8A continuous) per channel and supply voltages ranging from 8V to 52V. The device is equipped with two independent constant-off-time PWM current controllers, allowing precise current regulation and improved thermal efficiency. Integrated fast freewheeling diodes ensure effective synchronous rectification, while cross-conduction protection and slow decay mode further optimize safe and stable operation. Its Rds(on) value of 300mΩ typical delivers reduced conductive losses, making it suitable for demanding motion control requirements. The series also includes versatile logic inputs and enable pins for flexible interfacing with microcontrollers and control circuitry.

Electrical Characteristics and Thermal Ratings of the L6207PD013TR Series

Engineers evaluating the STMicroelectronics L6207PD013TR series will find an extensive suite of electrical parameters and absolute ratings to guide robust system design. The device accepts a supply voltage range from 8V to 52V, supporting both low- and high-voltage motor platforms. Each channel supports 2.8A continuous output with 5.6A peak pulses, limited by an internal overcurrent mechanism. Selectable switching frequencies up to 100kHz enable compatibility with a wide variety of motors and controllers.

From a thermal standpoint, L6207PD013TR leverages the PowerSO-36 exposed pad package for optimal heat dissipation, yielding typical junction-to-case thermal resistance of just 1°C/W. Engineers must manage board-level thermal dissipation based on application current and load profile, with options for multilayer, via-enhanced PCB layouts. The device safely operates within a temperature range of -25°C to 125°C, and shut-down is activated at 165°C junction temperature. For compliance and reliability, the L6207PD013TR series is RoHS3 compliant, REACH unaffected, and rated for MSL3 (168 hours).

Packaging Information and Pin Layout for the L6207PD013TR Series

The L6207PD013TR series is supplied in the compact PowerSO-36 package, measuring 0.433" (11.0mm) in width, with a slug internally connected to ground pins to facilitate thermal conduction into the PCB. The layout provides clear separation between bridge A and bridge B pins, including logic inputs, enable signals, reference voltage inputs, power outputs, and bootstrap supply connections for high-side MOSFET gate drive. Each bridge features dedicated sense pins for current feedback, RC timing pins to set PWM off-times, and comprehensive output pins to directly connect motor windings. The top-view pinout simplifies PCB routing and component placement in dense motor driver designs.

Safety Features in the L6207PD013TR Series

Reliability is a core concern for power electronics engineers, and the L6207PD013TR series integrates robust protection schemes. Non-dissipative overcurrent protection on high-side MOSFETs is implemented to safeguard against fault conditions without excessive power loss. Thermal shutdown provides automatic device disable at critical temperature thresholds, preserving IC longevity under overload or cooling failure. Undervoltage lockout further protects system integrity by preventing erratic operation due to inadequate supply voltage. These features, combined with current limiting and fault signal output, enable high-confidence designs for mission-critical motion control.

Use Cases for the L6207PD013TR Series

The L6207PD013TR series excels in both DC motor and bipolar stepper motor control, with particular strengths in applications demanding precision movement and high current capability. Examples include industrial conveyor systems, robotics grippers, automated guided vehicles (AGVs), and CNC machinery. The device’s PWM current control enables quiet and efficient operation in stepper motor platforms, while dual independent bridges support two separate motor channels or complex multi-phase drive schemes. System architects should note the suitability for voltage regulator designs where high-power switching and fault resilience are required.

Alternative or Substitute Models for the L6207PD013TR Series

For product selection and supply chain optimization, engineers may consider multiple equivalent or replacement models within STMicroelectronics’ motor driver family. The L6207D (SO24 package) offers similar functionality in an alternate footprint, ideal for projects with different board space constraints. When extended functionality, higher current rating, or additional diagnostics are required, higher-end members of STMicroelectronics’ dual or quad bridge motor driver portfolio may present attractive alternatives. Verification of pin-to-pin compatibility, thermal performance, and electrical characteristics is advised before substitution in existing designs.
