Product details
Overview
MAX16993AGJB/VY+ from Maxim Integrated is an AEC-Q100 qualified automotive PMIC integrating one high-voltage synchronous step-down controller (OUT1) and two cascaded low-voltage synchronous step-down converters (OUT2/OUT3), operating at 2.1MHz with 30µA quiescent current, 3.5V–36V input range, and -40°C to +125°C operation - designed for infotainment power rails in 12V/24V vehicle systems.
For engineers reviewing the MAX16993AGJB/VY+ datasheet, MAX16993AGJB/VY+ pinout, MAX16993AGJB/VY+ application, or MAX16993AGJB/VY+ equivalent, key selection criteria include its triple-output architecture with individual enable/reset, spread-spectrum EMI reduction, SYNC input for system clock alignment, and side-wettable QFND-EP package for automated optical inspection in automotive PCB assembly.
Technical Context
The MAX16993AGJB/VY+ implements a current-mode control architecture with forced-PWM and skip modes across all three channels. OUT1 uses an external high-side MOSFET and integrated low-side FET, while OUT2 and OUT3 integrate both high- and low-side FETs rated for 3A continuous output each.
Its oscillator supports pin-selectable 2.1MHz operation (CSEL1 = GND) or factory-programmed lower frequencies (1.05MHz/525kHz/420kHz/350kHz). Spread-spectrum modulation (SSEN = BIAS) varies fSW by ±3% at 4kHz, and SYNC input accepts 1.7–2.4MHz external clocks for deterministic noise suppression in multi-rail systems.
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 | 2.1MHz (pin-selectable); eliminates AM-band interference and permits <10mm² inductor footprint |
| Quiescent Current | 30µA with OUT1 enabled - meets automotive "always-on" low-power requirements for telematics and gateway modules |
| Output Channels | OUT1: HV buck controller (up to 5.5V); OUT2/OUT3: LV buck converters (0.8V–3.95V, up to 3A each) cascaded from OUT1 for >90% system efficiency |
| Thermal Protection | Thermal warning at +150°C and shutdown at +170°C with 15°C hysteresis - ensures reliability in under-hood environments |
| Reset Accuracy | RESET_ asserts when output drops 5–8% below nominal; timeout programmable from 0.1ms to 7.8ms - supports precise power sequencing in ADAS ECUs |
| AEC-Q100 Grade | Grade 0 (−40°C to +125°C junction) - qualified for engine compartment and front-end module applications |
Pinout & Package
MAX16993AGJB/VY+ is housed in a 32-pin side-wettable QFND-EP package (5mm × 5mm × 0.8mm) with exposed thermal pad, optimized for reflow soldering and automated optical inspection in automotive production.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSUP | Main high-voltage supply input | Accepts 3.5V–36V battery rail; includes undervoltage lockout at 4.5V startup threshold |
| EN1, EN2, EN3 | Independent digital enable inputs | Active-high logic; enables staged power-up of OUT1 → OUT2/OUT3 with fixed soft-start delays (4ms / 2.5ms) |
| OUT1, OUT2, OUT3 | Output voltage sense inputs | Connect directly to respective output nodes for feedback regulation; support fixed or resistor-divider-adjustable voltages |
| RESET1, RESET2, RESET3 | Open-drain reset outputs | Assert low during undervoltage or startup; timeout programmable per channel for sequenced microcontroller boot |
| SSEN, SYNC, CSEL1 | EMI and timing control inputs | SSEN enables spread-spectrum; SYNC accepts external clock (1.7–2.4MHz); CSEL1 selects 2.1MHz or factory-divided frequency |
Key Features
| Feature | Design Value |
|---|---|
| Triple-output cascaded architecture | OUT2/OUT3 powered from OUT1 reduces total solution size by 35% vs. discrete regulators and improves light-load efficiency via shared input capacitance |
| Side-wettable QFND-EP package | Enables automated optical inspection of solder joints on bottom-side pads - critical for zero-defect automotive manufacturing compliance |
| Individual enable and reset per channel | Supports independent power sequencing and fault isolation in multi-domain ECUs (e.g., separate resets for MCU core, I/O, and CAN transceiver rails) |
| Spread-spectrum + SYNC synchronization | Reduces peak radiated emissions by >10dBµV; allows deterministic noise placement across multiple synchronized PMICs in central gateway designs |
| Factory-trimmed output accuracy | ±3% over line/load/temperature without precision resistors - lowers BOM cost and design validation effort for 3.3V/5.0V/3.15V/1.8V standard rails |

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 |
|---|---|---|---|
| MAX20090ATPA/VY+ | Single 3.5V–36V buck controller (no integrated LV converters); supports 2.2MHz sync but lacks OUT2/OUT3 integration | Requires external dual-buck ICs for full 3-rail solution - increases board area and component count | Select when higher OUT1 current (>5A) or independent optimization of LV rails is required |
| TPS653211AQPWPRQ1 | Integrated 3-channel buck (2×2.5A + 1×1.5A); fixed 2.1MHz, no spread-spectrum, no CSEL1 frequency option | Lacks SSEN and programmable frequency; RESET outputs share common timeout - less flexible sequencing | Select when TI ecosystem compatibility or simplified qualification path is prioritized over EMI tuning flexibility |
Compared with MAX20090ATPA/VY+, MAX16993AGJB/VY+ delivers complete 3-rail integration in one package, reducing layout complexity and bill-of-materials cost; versus TPS653211AQPWPRQ1, it offers superior EMI control via spread-spectrum and pin-selectable frequency, critical for high-density infotainment layouts.

FAQ
What is the maximum continuous input voltage the MAX16993AGJB/VY+ can withstand?
The MAX16993AGJB/VY+ supports continuous operation up to 36V on VSUP and is protected against load-dump transients up to 42V for ≤50ns. This enables direct connection to 12V and 24V automotive battery systems without external transient protection circuitry, simplifying front-end design while maintaining robustness per ISO 7637-2.
Does the MAX16993AGJB/VY+ support independent power sequencing between its three outputs?
Yes, the MAX16993AGJB/VY+ provides independent EN1, EN2, and EN3 inputs and individual open-drain RESET1, RESET2, and RESET3 outputs. Each reset timeout is programmable (0.1ms–7.8ms), allowing precise, staggered power-up of microcontroller cores, peripherals, and communication interfaces - essential for reliable boot in automotive ECUs.
How does the spread-spectrum feature of the MAX16993AGJB/VY+ reduce EMI?
The MAX16993AGJB/VY+ spreads its 2.1MHz switching frequency by ±3% (±63kHz) at a 4kHz modulation rate when SSEN is tied to BIAS. This distributes energy across a wider bandwidth, lowering peak radiated emissions by >10dBµV - a critical advantage in space-constrained infotainment head units where metal shielding is impractical.
Can the MAX16993AGJB/VY+ operate with only OUT1 enabled while keeping OUT2 and OUT3 disabled?
Yes. The MAX16993AGJB/VY+ allows OUT1 to operate independently: EN1 high enables the high-voltage controller, while EN2 and EN3 held low disable OUT2 and OUT3. In this state, the device draws only 30µA quiescent current and maintains BIAS regulation - ideal for low-power wake-up circuits in gateway ECUs.
What package variant does MAX16993AGJB/VY+ use, and why is it automotive-qualified?
MAX16993AGJB/VY+ uses a 32-pin side-wettable QFND-EP package (5mm × 5mm × 0.8mm) with exposed thermal pad. Its side-wettable leads enable automated optical inspection (AOI) of solder fillets - a mandatory requirement for zero-defect automotive manufacturing - while the thermal pad ensures efficient heat dissipation in high-ambient under-hood environments.
