Renesas SLG47105V-TRN

Overview

SLG47105V-TRN from Renesas Electronics is a one-time programmable (OTP) mixed-signal matrix IC with integrated high-voltage bridge drivers, dual PWM macrocells, and configurable logic. It operates across dual supplies (2.5–5.0 V on VDD; 3.3–12.0 V on VDD2), delivers up to 2 A peak per full bridge at 5 V VDD2, and integrates over-current, thermal, and UVLO protections. It is used in motor drive modules requiring compact, programmable load control with real-time current sensing and fault reporting.

For engineers reviewing the SLG47105V-TRN datasheet, SLG47105V-TRN pinout, SLG47105V-TRN application, or SLG47105V-TRN equivalent, key selection criteria include its STQFN-20 package, dual VDD support, HV GPO slew rate modes (motor driver vs. MOSFET pre-driver), integrated differential amplifier for speed control, and I²C programmability for dynamic duty cycle updates.

Technical Context

The SLG47105V-TRN implements a reconfigurable interconnect matrix linking GPIOs, HV outputs, analog comparators, PWM generators, and macrocells. Its two independent PWM macrocells support 8-bit/7-bit resolution, 16 preset duty-cycle registers, and phase-correct operation - enabling sine-wave generation and dead-band control for half/full-bridge switching.

It features two current sense comparators with dynamic Vref mode, a differential amplifier with integrator for closed-loop motor speed regulation, and dual oscillators (2.048 kHz and 25 MHz) for timing flexibility. Protection circuitry includes per-bridge OCP, UVLO, TSD, and fault signaling via dedicated pins.

FAQ

What is the maximum output voltage supported by SLG47105V-TRN on its HV pins?

The SLG47105V-TRN supports VDD2 up to 12.0 V (±10 %), meaning its high-voltage outputs can swing up to 12 V. This enables direct drive of 12 V solenoids, brushed DC motors, and LED strings without external level-shifting circuitry. The device maintains specified performance - including R_DS(ON), current rating, and protection thresholds - across the full 3.3–12.0 V VDD2 range.

Does SLG47105V-TRN support I²C communication for runtime configuration?

Yes, SLG47105V-TRN includes a fully functional I²C interface compliant with standard-mode (100 kHz) and fast-mode (400 kHz) protocols. It allows real-time read/write access to PWM registers, fault status bits, oscillator settings, and macrocell configurations - enabling dynamic adjustments such as duty cycle changes or protection threshold updates without resetting the SLG47105V-TRN.

How does the SLG47105V-TRN implement over-current protection?

The SLG47105V-TRN uses dedicated SENSE_A and SENSE_B inputs connected to internal current sense comparators. Each comparator monitors voltage across an external shunt resistor and triggers OCP when current exceeds the threshold set by dynamic Vref scaling. Upon detection, the corresponding FAULT_A or FAULT_B pin asserts low, and the affected bridge is disabled - all within hardware, without MCU involvement.

Can SLG47105V-TRN generate sine-wave-like drive signals for smooth motor operation?

Yes, SLG47105V-TRN supports this via its two PWM macrocells operating in "Preset Registers Mode" with 16 user-programmable duty-cycle values. By sequencing these registers under timer or external trigger control, the SLG47105V-TRN synthesizes trapezoidal or near-sine waveforms - ideal for reducing torque ripple in brushed DC or simple stepper motor drives.

What thermal management features are built into SLG47105V-TRN?

The SLG47105V-TRN integrates thermal shutdown (TSD) with hysteresis and automatic recovery. When die temperature exceeds the trip point (typically 150 °C), all HV outputs disable and FAULT pins assert. After cooling below the release threshold (~135 °C), operation resumes autonomously. The STQFN-20 package includes an exposed thermal pad to enhance PCB heat dissipation - critical for sustained 2 A RMS operation.
