Product details
Overview
MAX16993AGJG/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 delivers 3.3V or 5.0V fixed OUT1 output, supports 0.8V–3.95V adjustable OUT2/OUT3 outputs, achieves ≤30µA quiescent current, and withstands 42V load-dump transients - enabling compact, robust power for ADAS camera modules and infotainment head units.
For engineers reviewing the MAX16993AGJG/VY+ datasheet, MAX16993AGJG/VY+ pinout, MAX16993AGJG/VY+ application, or MAX16993AGJG/VY+ equivalent, key selection criteria include its -40°C to +125°C operation, side-wettable QFND-EP 5mm × 5mm package, individual RESET_ outputs per channel, spread-spectrum enable (SSEN), and SYNC input for system-level clock synchronization in ECU designs.
Technical Context
The MAX16993AGJG/VY+ implements a current-mode architecture with forced-PWM and skip modes across all three regulators. Its OUT1 controller operates from 3.5V–36V input and integrates high-side (DH1) and low-side (DL1) gate drivers with 1–4Ω on-resistance, while OUT2/OUT3 are cascaded from OUT1 and feature integrated 50–110mΩ FETs delivering up to 3A each.
It provides independent enable inputs (EN1/EN2/EN3), open-drain RESET_ outputs with programmable timeout (0.1ms–7.8ms), overtemperature shutdown at +170°C, and short-circuit protection via current-sense inputs (CS1, OUT1). The BIAS LDO supplies internal circuitry and transitions from 5V to OUT1 voltage post-soft-start.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.5V–36V continuous; survives 42V load-dump transients - enables direct connection to automotive battery without external protection. |
| Switching Frequency | Pin-selectable 2.1MHz or factory-set 1.05/0.525/0.42/0.35MHz - allows AM-band avoidance and optimized efficiency vs. size trade-offs. |
| Quiescent Current | 30µA with DC-DC enabled - meets automotive always-on requirements while minimizing standby power loss. |
| Output Channels | OUT1: up to 5.0V/3.75A; OUT2/OUT3: 0.8V–3.95V/3.0A each, cascaded from OUT1 - reduces component count and improves overall system efficiency. |
| Thermal Rating | AEC-Q100 Grade 0 (–40°C to +125°C ambient); thermal shutdown at +170°C with 15°C hysteresis - ensures reliability in under-hood environments. |
| Package | 32-pin side-wettable QFND-EP (5mm × 5mm × 0.8mm); exposed pad tied to GND - supports automated optical inspection (AOI) and enhances thermal dissipation (θJA = 37°C/W). |
Pinout & Package
MAX16993AGJG/VY+ uses a 32-pin side-wettable QFND-EP package (5mm × 5mm × 0.8mm) with exposed thermal pad connected to GND. Pin functions are validated per Maxim's official datasheet Rev 14 (12/2016).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSUP | Main HV input supply | Accepts 3.5V–36V automotive battery; includes UVLO startup threshold at 4.5V and 42V transient tolerance. |
| EN1 / EN2 / EN3 | Independent enable inputs | Active-high digital controls; EN1 enables entire PMIC, EN2/EN3 independently activate OUT2/OUT3 after OUT1 regulation. |
| RESET1 / RESET2 / RESET3 | Open-drain reset outputs | Assert low when respective output drops >6% below nominal; timeout programmable (0.1–7.8ms) for sequenced system boot. |
| CSEL1 / SSEN / SYNC | Configuration & control I/O | CSEL1 selects 2.1MHz or divided frequency; SSEN enables ±6% spread-spectrum; SYNC accepts 1.7–2.4MHz external clock for system-wide noise reduction. |
| OUT1 / OUT2 / OUT3 | Output voltage sense inputs | Connect directly to respective output nodes for feedback; support fixed (3.3V/5.0V) or resistor-divider-adjustable (0.8V–5.5V) regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Triple-output architecture with cascaded topology | OUT2/OUT3 powered from OUT1 reduces total solution size by eliminating separate input capacitors and improves light-load efficiency. |
| Individual soft-start timing | 4ms for OUT1, 2.5ms for OUT2/OUT3 - prevents inrush current overload during cold cranking and enables precise power sequencing. |
| Spread-spectrum modulation | SSEN pin enables ±6% frequency dithering at 4kHz - lowers peak EMI by >10dB without requiring external filters or layout changes. |
| Factory-trimmed output accuracy | ±3% over line/load/temperature for fixed outputs - eliminates need for precision resistors and simplifies BOM for automotive production. |
| Robust fault protection | Overcurrent (via CS1/OUT1), overtemperature (+170°C shutdown), undervoltage lockout (2.7V PV threshold) - ensures fail-safe operation in harsh vehicle environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multichannel automotive DC-DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX20096ATPA/VY+ | 3-channel buck with 2.2MHz max fSW, 3.5V–36V input, but no spread-spectrum; requires external compensation for all channels. | Lacks SSEN pin and factory-trimmed fixed outputs - needs more external components for EMI compliance and voltage accuracy. | Choose when lower cost and simpler compensation are prioritized over EMI performance and production-ready accuracy. |
| TPS653221AQPWPRQ1 | Triple-buck with 2.1MHz, AEC-Q100, but only 1.5A per low-voltage channel; no CSEL1 frequency division option. | Lower output current capability and no pin-selectable frequency scaling - limits use in high-power camera or radar modules. | Prefer for cost-sensitive body electronics where 1.5A per rail suffices and frequency flexibility is unnecessary. |
Compared with MAX20096ATPA/VY+ and TPS653221AQPWPRQ1, the MAX16993AGJG/VY+ uniquely combines 3A per low-voltage rail, pin-selectable 2.1MHz operation, integrated spread-spectrum, and factory-trimmed ±3% accuracy - making it optimal for high-reliability ADAS and infotainment systems demanding minimal BOM and proven EMI performance.

FAQ
What is the maximum input voltage the MAX16993AGJG/VY+ can withstand during load-dump events?
The MAX16993AGJG/VY+ is rated to withstand load-dump transients up to 42V on the VSUP pin. This specification is validated per ISO 7637-2 Pulse 5a testing conditions and allows direct connection to automotive 12V battery systems without additional transient voltage suppression components. The device remains functional and protected during these events, ensuring robustness in real-world vehicle environments.
Does the MAX16993AGJG/VY+ support synchronous clocking with other power supplies in a system?
Yes, the MAX16993AGJG/VY+ supports system-level synchronization via its SYNC pin. When configured as an input, it accepts external clock signals from 1.7MHz to 2.4MHz with 50% duty cycle, enabling forced-PWM operation and phase alignment with other converters. This capability reduces beat frequencies and aggregate EMI, making the MAX16993AGJG/VY+ ideal for multi-rail automotive systems requiring coordinated switching.
How does the MAX16993AGJG/VY+ achieve low quiescent current in automotive always-on applications?
The MAX16993AGJG/VY+ achieves ≤30µA quiescent current through optimized bias circuitry and adaptive gate-drive control. With only the high-voltage controller (OUT1) enabled and no load, internal regulators enter ultra-low-power states while maintaining voltage monitoring and reset functionality. This behavior is verified across the full –40°C to +125°C temperature range, meeting stringent automotive IQ requirements for body control and telematics modules.
Can the output voltages of the MAX16993AGJG/VY+ be adjusted externally, or are they factory-fixed?
The MAX16993AGJG/VY+ supports both factory-fixed and externally adjustable outputs. OUT1 offers 3.3V or 5.0V fixed options (selected via FB1 connection), or 3.0V–5.5V adjustment using a resistor divider. OUT2/OUT3 provide 0.8V–3.95V programmability via external dividers, with factory-trimmed versions achieving ±3% accuracy over temperature and load - eliminating need for precision resistors in production designs.
What thermal management features does the MAX16993AGJG/VY+ include to ensure reliability in under-hood applications?
The MAX16993AGJG/VY+ incorporates thermal warning at +150°C and shutdown at +170°C with 15°C hysteresis, plus a low θJA of 37°C/W in its side-wettable QFND-EP package. The exposed thermal pad must be soldered to a solid GND plane, and internal thermal sensing triggers immediate current limiting before shutdown. These features are AEC-Q100 validated and ensure sustained operation in high-ambient environments like engine compartments and dashboard assemblies.
