Product details
Overview
MAX16993AGJE/VY+ from Maxim Integrated is an AEC-Q100 qualified automotive PMIC integrating one high-voltage synchronous step-down controller (OUT1) and two low-voltage synchronous step-down converters (OUT2/OUT3), all operating up to 2.1MHz. It accepts 3.5V–36V input, delivers ≤5.0V/≤3.95V outputs with ±2.5% accuracy, consumes only 30µA quiescent current, and supports load-dump transients up to 42V - enabling compact, robust power rails for ADAS camera modules and infotainment head units.
For engineers reviewing the MAX16993AGJE/VY+ datasheet, MAX16993AGJE/VY+ pinout, MAX16993AGJE/VY+ application, or MAX16993AGJE/VY+ equivalent, key selection criteria include its 32-pin side-wettable QFND-EP package, cascaded OUT2/OUT3 architecture improving efficiency over discrete solutions, spread-spectrum enable (SSEN) for EMI reduction, individual RESET_ outputs with programmable timeout, and factory-set or pin-selectable switching frequencies (2.1MHz, 1.05MHz, 525kHz, 420kHz, 350kHz).
Technical Context
The MAX16993AGJE/VY+ implements a current-mode control architecture with forced-PWM and skip modes, supporting synchronization via SYNC input (1.7–2.4MHz range) and spread-spectrum modulation (±6% frequency dither at 4kHz). Its OUT1 controller uses external high-side/low-side MOSFETs, while OUT2 and OUT3 integrate 3A FETs and operate from OUT1's output - eliminating intermediate LDOs and reducing thermal overhead in multi-rail automotive systems.
Each buck channel features independent enable inputs (EN1/EN2/EN3), open-drain RESET_ outputs with 0.1ms–7.8ms programmable assertion time, and overtemperature shutdown (170°C) with 15°C hysteresis. The BIAS linear regulator provides 5V internal supply during startup, then transitions to OUT1 voltage post-soft-start - ensuring stable biasing across wide input transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.5V to 36V continuous; withstands 42V load-dump transients - enables direct connection to automotive battery without pre-regulator. |
| Switching Frequency | Pin-selectable 2.1MHz or factory-set 1.05MHz/525kHz/420kHz/350kHz - allows AM-band avoidance or efficiency optimization. |
| Quiescent Current | 30µA with OUT1 enabled - meets automotive "always-on" low-power requirements for telematics and gateway ECUs. |
| Output Accuracy | ±2.5% for OUT1 (PWM mode), ±3.0% for OUT2/OUT3 - ensures reliable microcontroller and sensor rail regulation across -40°C to +125°C. |
| Thermal Protection | Thermal shutdown at +170°C with 15°C hysteresis - prevents latch-up during sustained overload in under-hood environments. |
| Package | 32-pin side-wettable QFND-EP (5mm × 5mm × 0.8mm); θJA = 37°C/W - supports automated optical inspection and high-power dissipation in compact layouts. |
| AEC-Q100 Grade | Grade -40°C to +125°C ambient operation - certified for passenger compartment and engine bay applications. |
Pinout & Package
MAX16993AGJE/VY+ is housed in a 32-pin side-wettable QFND-EP package (5mm × 5mm × 0.8mm) with exposed pad connected to GND for thermal management. Pin functions are validated per Maxim Integrated datasheet Rev 14 (12/2016).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSUP | Main high-voltage supply input | Accepts 3.5V–36V battery input; includes undervoltage lockout (4.5V typ startup threshold) and 42V transient protection. |
| EN1 / EN2 / EN3 | Independent enable inputs | Active-high digital controls; EN1 enables entire PMIC, EN2/EN3 independently activate OUT2/OUT3 after OUT1 soft-start completes. |
| OUT1 / OUT2 / OUT3 | Output voltage sense inputs | Connect directly to respective output nodes for feedback regulation; support fixed or resistor-divider adjustable voltages (e.g., 3.3V, 5.0V, 1.8V, 3.15V). |
| RESET1 / RESET2 / RESET3 | Open-drain reset outputs | Assert low when corresponding output drops >6% below nominal; timeout programmable (0.1–7.8ms) for sequenced system boot. |
| SSEN / CSEL1 / SYNC | Control configuration inputs | SSEN enables spread-spectrum EMI reduction; CSEL1 selects 2.1MHz or factory-divided frequency; SYNC synchronizes to external clock or enables skip mode. |
Key Features
| Feature | Design Value |
|---|---|
| Cascaded dual low-voltage converters | OUT2/OUT3 powered directly from OUT1 output - eliminates intermediate LDOs, improves overall system efficiency by ≥8% vs. discrete buck + LDO chains. |
| Individual soft-start timing | 4ms for OUT1, 2.5ms for OUT2/OUT3 - enforces controlled power-up sequencing to prevent inrush current conflicts in multi-processor systems. |
| Spread-spectrum enable (SSEN) | Reduces peak radiated emissions by spreading oscillator frequency ±6% at 4kHz - meets CISPR 25 Class 5 requirements without added shielding. |
| Factory-trimmed output options | Fixed 3.3V, 5.0V, 3.15V, 1.8V outputs available - achieves ±3% regulation over temperature/load without precision external resistors. |
| Robust fault protection | Overcurrent limiting (100–150mV CS1 threshold), thermal shutdown (+170°C), and output overvoltage detection - ensures fail-safe operation in harsh automotive environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multichannel automotive DC-DC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX20096ATPA/VY+ | Single 3.5V–36V buck controller (no integrated secondary converters); supports 2.2MHz sync, lower IQ (18µA), but requires external buck stages for multi-rail outputs. | Used where design flexibility outweighs BOM count - e.g., custom 1.0V core rail with external FETs for higher current. | Select MAX20096ATPA/VY+ when OUT2/OUT3 current exceeds 3A or when layout requires separate thermal management of each converter stage. |
| TPS650331ARSLR | Triple-output PMIC with integrated 3A/2A/1.5A FETs; fixed 3.3V/1.8V/1.2V outputs; no spread-spectrum; 45µA IQ; supports only 2.2MHz sync (no pin-selectable frequencies). | Targeted at TI-based Jacinto processors; lacks programmable RESET timeout and load-dump tolerance beyond 40V. | Select TPS650331ARSLR for cost-sensitive infotainment designs using TI SoCs where EMI requirements are less stringent and fixed-rail simplicity is prioritized. |
Compared with MAX16993AGJE/VY+, MAX20096ATPA/VY+ offers lower quiescent current but requires external converters for multi-rail generation, while TPS650331ARSLR provides fixed outputs with simpler configuration but lacks spread-spectrum and 42V transient capability - making MAX16993AGJE/VY+ optimal for high-reliability, EMI-sensitive automotive systems needing flexible, sequenced, and protected power delivery.

FAQ
What is the maximum input voltage rating and transient tolerance for MAX16993AGJE/VY+?
The MAX16993AGJE/VY+ supports a continuous input voltage range of 3.5V to 36V and is protected against load-dump transients up to 42V for ≤50ns. This rating is validated per ISO 16750-2 and enables direct connection to automotive battery systems without external transient suppression components in most implementations.
Does MAX16993AGJE/VY+ support synchronization to an external clock source?
Yes, MAX16993AGJE/VY+ supports external clock synchronization via the SYNC pin, which accepts input frequencies from 1.7MHz to 2.4MHz with 50% duty cycle. When configured as an input, SYNC enables fixed-frequency forced-PWM operation and reduces system-level noise through deterministic switching alignment.
How does the cascaded architecture of OUT2 and OUT3 improve efficiency in MAX16993AGJE/VY+?
In MAX16993AGJE/VY+, OUT2 and OUT3 are powered directly from the output of OUT1 rather than from the main VSUP rail. This cascaded topology reduces conduction losses and improves overall system efficiency by up to 8% compared to discrete buck + LDO solutions, especially at medium-to-high load currents typical in automotive infotainment and ADAS subsystems.
What are the available output voltage options for MAX16993AGJE/VY+?
MAX16993AGJE/VY+ supports both factory-trimmed fixed outputs (e.g., 3.3V, 5.0V, 3.15V, 1.8V) and resistor-divider adjustable outputs. For OUT1, the feedback reference is 1.0V (typ), enabling 3.0V–5.5V adjustment; for OUT2/OUT3, the reference is 0.815V (typ), supporting 0.8V–3.95V regulation with ±3% accuracy over temperature and load.
Is MAX16993AGJE/VY+ qualified for automotive applications?
Yes, MAX16993AGJE/VY+ is AEC-Q100 qualified for Grade 1 (-40°C to +125°C ambient) operation and designed to meet automotive reliability standards including ISO 16750-2 (electrical loads) and ISO 16750-4 (mechanical loads).
