Product details
Overview
MLX83100LGO-DDA-000-SP from Melexis is an AEC-Q100 qualified automotive 2-phase DC pre-driver IC designed to control four external N-channel power FETs in brushed DC motor applications. It integrates high-side/low-side gate drivers with bootstrap and trickle charge pump, a programmable current sense amplifier (8×–48× gain, <1 µs settling), and serial diagnostics via ICOM PWM interface. It operates from 4.5 V–28 V supply, supports 100% PWM duty cycle, and delivers up to 0.45 A peak gate drive current per channel.
For engineers reviewing the MLX83100LGO-DDA-000-SP datasheet, pinout, applications, or equivalent options, this device serves as a configurable, fault-aware pre-driver for 12 V–28 V automotive brushed motor systems requiring precise torque control, reverse-polarity protection, and diagnostic feedback without MCU pin overhead.
Technical Context
The MLX83100LGO-DDA-000-SP implements dual-phase gate driving using two independent half-bridge channels (PHASE2/PHASE3), each with dedicated high-side (GATET2/GATET3) and low-side (GATEB2/GATEB3) outputs. Its trickle charge pump enables stable 12 V gate drive down to 4.5 V VSUP while supporting 100% PWM operation via bootstrap capacitor management.
It embeds a fast, low-offset current sense amplifier (±7.6 mV offset, <1 µs settling) with programmable gain and analog output (ISENSE), alongside comprehensive diagnostics including VDS/VGS monitoring, overtemperature warning (168 °C–185 °C window), and supply rail monitoring (VSUP, VREG, VBOOST) reported via bidirectional ICOM PWM interface.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-phase brushed DC pre-driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8305PAPR | 3-phase pre-driver with integrated current shunt amplifiers; no EEPROM configuration; requires external VREF for CSA | Targeted at 3-phase BLDC systems; lacks reverse-polarity N-FET protection mode and VDS monitoring per FET | Choose DRV8305PAPR only if migrating to 3-phase architecture or needing higher integration without EEPROM customization |
| MPQ6535-AEC1 | Single-channel 2-phase pre-driver with integrated 12 V LDO; no trickle charge pump; max VSUP = 20 V; no VDS monitoring | Designed for lower-voltage 12 V pumps/fans; lacks diagnostic depth and low-voltage robustness below 7 V | Choose MPQ6535-AEC1 for cost-sensitive, non-safety-critical 12 V applications where 4.5 V operation and per-FET VDS monitoring are unnecessary |

FAQ
What is the minimum operating supply voltage for MLX83100LGO-DDA-000-SP?
The MLX83100LGO-DDA-000-SP operates functionally from 4.5 V to 28 V on VSUP. Below 7 V, it enters extended low-range mode with reduced gate drive voltage but maintains full functionality via its trickle charge pump. Absolute maximum rating is 45 V for transient load dump conditions.
Does MLX83100LGO-DDA-000-SP support 100% PWM duty cycle?
Yes, MLX83100LGO-DDA-000-SP supports true 100% PWM operation using its trickle charge pump to sustain bootstrap capacitor voltage, eliminating the need for external boost circuitry. This is confirmed in the datasheet's General Description and validated across the 4.5 V–28 V VSUP range.
How does the current sense amplifier in MLX83100LGO-DDA-000-SP interface with the MCU?
The MLX83100LGO-DDA-000-SP provides an analog ISENSE output referenced to VDD, with programmable gain (8×–48×) and <1 µs settling time. The MCU reads this voltage directly via ADC; no external op-amp or signal conditioning is required for torque feedback in brushed DC motor control loops.
What diagnostic information does MLX83100LGO-DDA-000-SP report via the ICOM pin?
The MLX83100LGO-DDA-000-SP reports under/over voltage (VSUP, VREG, VBOOST), overtemperature (168 °C–185 °C window), VDS and VGS faults per external FET, and configuration errors via PWM-encoded duty cycle on the ICOM pin - all without requiring SPI communication or additional MCU GPIOs.
Is MLX83100LGO-DDA-000-SP pin-compatible with earlier MLX83100 variants?
Yes, MLX83100LGO-DDA-000-SP shares identical pinout, package (TSSOP-EP), and electrical characteristics with other MLX83100 variants in the GO package. The DDA-000 option code denotes factory-programmed EEPROM configuration, not a pinout change - enabling drop-in replacement in existing designs.
