Product details
Overview
MLX83100LGO-DDA-000-RE from Melexis is an AEC-Q100 qualified automotive 2-phase DC pre-driver IC designed to control four external N-channel FETs in brushed DC motor applications. It delivers 100% PWM operation via integrated trickle charge pump, supports 4.5V–28V battery supply, integrates a programmable current sense amplifier (gain 8×–48×, settling <1 µs), and provides diagnostics via ICOM PWM interface for use in engine cooling fans and HVAC blowers.
For engineers reviewing the MLX83100LGO-DDA-000-RE datasheet, pinout, applications, or equivalent options, key selection considerations include bootstrap-based high-side gate drive capability, VDS/VGS monitoring for FET health, EEPROM-configurable dead time and diagnostics, and compliance with automotive 12V/24V systems requiring <30 µA sleep current.
Technical Context
The MLX83100LGO-DDA-000-RE implements dual-phase gate driver logic with programmable dead time (0.00–6.90 µs) and shoot-through protection. Its charge pump operates in two modes-ground-referenced (CP Mode 0) or supply-referenced (CP Mode 1)-enabling reverse-polarity N-FET protection and low-voltage operation down to 4.5V.
It integrates a fast current sense amplifier (settling <1 µs, offset ±7.6 mV, drift ±10 µV/°C) with programmable gain and a bidirectional serial diagnostics interface (ICOM) delivering fault codes via PWM duty cycle. All configuration-including driver timing, VDS monitor thresholds, and diagnostic enablement-is stored in on-chip EEPROM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 4.5V–28V functional; 45V absolute max - supports 12V/24V automotive battery systems with load dump tolerance. |
| Sleep Current | <30 µA at VSUP - enables always-on motor control nodes without battery drain. |
| Gate Drive Capability | Supports 4× 500 nC N-FETs at 20 kHz PWM - sufficient for high-torque automotive pumps and fans. |
| Current Sense Accuracy | ±7.6 mV input offset, ±10 µV/°C drift, <1 µs settling - enables precise torque and stall detection in closed-loop motor control. |
| Diagnostics Interface | ICOM PWM output (10.6–115 kHz) with fault-coded duty cycle - eliminates need for dedicated MCU GPIOs or SPI lines. |
| EEPROM Configurability | User-programmable dead time, VDS monitor threshold (0.4–2.3 V), blanking time, and CP mode - reduces BOM count and enables one-hardware-fits-many applications. |
| Package | 28-pin TSSOP-EP (4.4 × 9.8 mm, exposed pad) - thermally optimized for automotive under-hood ambient up to +150°C. |
| AEC-Q100 Grade | Grade 0 (−40°C to +150°C ambient), junction rated to +175°C - qualified for engine bay and EPS module placement. |
Pinout & Package
MLX83100LGO-DDA-000-RE is housed in a 28-pin TSSOP-EP package with exposed thermal pad (GO suffix). Pin functions are validated per Melexis Datasheet Rev. 5.11, Table 7-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FETT2 / FETT3 | High-side PWM inputs | Active-high logic signals from MCU; level-shifted to drive bootstrap gate drivers for PHASE2/PHASE3. |
| FETB2 / FETB3 | Low-side PWM inputs | Active-low logic signals; directly drive low-side FET gates with internal pull-down resistors (90–410 kΩ). |
| GATET2 / GATET3 | High-side gate outputs | Bootstrap-supplied outputs capable of sourcing/sinking ±450 mA peak; support 100% duty cycle via trickle charge pump. |
| GATEB2 / GATEB3 | Low-side gate outputs | Directly driven from VREG (11–13 V); ON resistance ≤30 Ω ensures fast switching into 500 nC FETs. |
| ISENSE / IBP / IBM / VREF | Current sense interface | Differential inputs with programmable gain; ISENSE output is rail-to-rail (GND to VDD) with 8 V/µs slew rate. |
| ICOM | Bidirectional diagnostics port | Open-drain PWM output (fast/slow modes) and SPI CSB/MOSI/MISO shared pin - enables compact MCU interface. |
| VBOOST / VREG / CP / CP2 / CP3 | Charge pump subsystem | VBOOST supplies VREG; CP2/CP3 connect to bootstrap capacitors; CP pin connects floating capacitor for voltage doubling. |
| VSUP / VBATF / DGND / AGND | Power & sensing rails | VSUP = main battery input (4.5–28 V); VBATF feeds VDS monitoring; separate analog/digital grounds reduce noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Trickle charge pump architecture | Enables 100% PWM operation with bootstrap high-side drivers by replenishing gate charge between cycles, even at VSUP = 4.5 V. |
| Programmable VDS monitoring | Eight selectable thresholds (0.40–2.30 V) with blanking time options (0.6–6.8 µs) allow robust short-circuit and open-load detection per FET. |
| Integrated 12 V regulator (VREG) | Delivers stable 11–13 V at up to 40 mA (CP Mode 0) to power low-side drivers and bootstrap circuits - eliminates external LDO. |
| EEPROM-based configuration | Stores driver timing, diagnostics settings, and CP mode - removes need for external configuration resistors or firmware initialization code. |
| Fast current sense amplifier | Settles in <1 µs with ±7.6 mV offset and ±10 µV/°C drift - supports high-bandwidth motor current control loops up to 20 kHz PWM. |
| Serial diagnostics via ICOM | Single-wire PWM interface reports overvoltage, undervoltage, overtemperature, VDS/VGS faults - reduces MCU pin count and simplifies error handling. |
Applications
| Engine Cooling Fan Control | HVAC Blower Motor |

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 |
|---|---|---|---|
| DRV8305-Q1 | 3-phase pre-driver with integrated FET drivers; no on-chip current sense amplifier; requires external shunt and op-amp. | Targeted at 3-phase BLDC systems; lacks EEPROM configurability and VDS monitoring per FET. | Select DRV8305-Q1 only when scaling to 3-phase motors or when external current sensing is preferred for higher accuracy. |
| TLE9201SG | 2-phase pre-driver with fixed dead time (no EEPROM programming); no trickle charge pump - limited to >7 V operation. | Designed for cost-sensitive 12V fans/pumps; lacks reverse-polarity protection mode and programmable VDS thresholds. | Choose TLE9201SG for simpler, lower-cost designs where 100% PWM and sub-7V operation are not required. |
Compared with DRV8305-Q1 and TLE9201SG, the MLX83100LGO-DDA-000-RE uniquely combines EEPROM-configurable diagnostics, trickle charge pump for full 4.5V–28V operation, and integrated current sense amplifier - making it optimal for automotive brushed DC motor modules requiring functional flexibility and minimal external components.

FAQ
What is the minimum supply voltage for continuous operation of the MLX83100LGO-DDA-000-RE?
The MLX83100LGO-DDA-000-RE supports continuous operation down to 4.5 V using its trickle charge pump in CP Mode 0. Below this, functionality is not guaranteed; the absolute minimum for transient survival is −0.3 V, and the absolute maximum is 45 V for <500 ms during load dump events.
Does the MLX83100LGO-DDA-000-RE support 100% duty cycle PWM for high-side FETs?
Yes, the MLX83100LGO-DDA-000-RE supports 100% duty cycle PWM for high-side FETs via its trickle charge pump, which continuously replenishes bootstrap capacitor charge even when the low-side FET is off - eliminating the need for external charge pumps or complex timing constraints.
How is diagnostics information communicated from the MLX83100LGO-DDA-000-RE to the host MCU?
The MLX83100LGO-DDA-000-RE communicates diagnostics via the ICOM pin using a configurable PWM signal: fault type is encoded in duty cycle (e.g., 25% = overvoltage, 50% = overtemperature), and frequency is selectable between 10.6–14.4 kHz (slow) or 85–115 kHz (fast) via EEPROM configuration.
Can the MLX83100LGO-DDA-000-RE be used with 5 V microcontrollers?
Yes, the MLX83100LGO-DDA-000-RE is explicitly compatible with 3.3 V and 5 V microcontrollers: its digital inputs (FETT2/FETT3/FETB2/FETB3/EN) accept logic high ≥80% VDD and logic low ≤20% VDD, and VDD may be supplied at either 3.3 V or 5 V within 3–5.5 V range.
What is the purpose of the VBATF pin on the MLX83100LGO-DDA-000-RE?
The VBATF pin on the MLX83100LGO-DDA-000-RE provides a dedicated connection to the battery rail for accurate VDS monitoring of external FETs. It enables precise drain-source voltage measurement independent of VSUP fluctuations, supporting reliable short-circuit and open-load detection in safety-critical motor control.
