Product details
Overview
MAX6795TPVD1+T from Maxim Integrated is a single-output, high-voltage linear regulator with integrated supervisory functions, designed for automotive systems requiring robust operation under load-dump (up to 72V) and ultra-low quiescent current (68μA). It delivers up to 300mA at fixed 5V output, features active-low push-pull RESET with 4.625V threshold, and supports watchdog timeout (280ms min) and hold functionality for self-holding ignition circuits.
For engineers reviewing the MAX6795TPVD1+T datasheet, MAX6795TPVD1+T pinout, MAX6795TPVD1+T application, or MAX6795TPVD1+T equivalent, key selection criteria include its AEC-Q100-qualified 5mm × 5mm TQFN package, -40°C to +125°C operation, 420mV dropout at 100mA, thermal/short-circuit protection, and compatibility with reverse-battery pFET gate drive via GATEP pin.
Technical Context
The MAX6795TPVD1+T implements a single high-side linear regulator with internal p-channel pass device, supporting input voltages from 5V to 72V and delivering regulated 5V output with ±2.5% accuracy over temperature and load. Its supervisory block integrates a precision reset comparator (92.5% of VOUT threshold), capacitor-adjustable reset timeout (35μs–200ms), and fixed 280ms watchdog timeout with disable capability via WD-DIS.
It includes ENABLE and HOLD inputs enabling ignition-controlled latching behavior: once enabled, asserting HOLD low maintains regulation even after ENABLE returns low; releasing HOLD shuts down the output. The GATEP pin drives an external pFET for reverse-battery protection, eliminating series diode losses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 5V to 72V - withstands automotive load-dump transients without external clamping |
| Output Voltage | Fixed 5.0V (±2.5%) - meets standard microcontroller and sensor rail requirements |
| Max Output Current | 300mA continuous - sufficient for MCU core + peripheral power in body control modules |
| Quiescent Current | 68μA typical - enables always-on functionality with minimal battery drain |
| Dropout Voltage | 420mV at 100mA - maintains regulation down to VIN = 5.42V at full load |
| Reset Threshold | 4.625V (92.5% of 5V) - asserts RESET before MCU brownout during undervoltage events |
| Operating Temp | -40°C to +125°C - qualified for under-hood automotive environments |
| Package | 20-pin TQFN-EP (5mm × 5mm) - thermally enhanced for 2.7W dissipation at high ambient |
Pinout & Package
MAX6795TPVD1+T is housed in a 20-pin, 5mm × 5mm thermally enhanced TQFN package with exposed pad (EP) connected internally to GND. The EP must be soldered to the PCB ground plane for optimal thermal performance and EMI reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1,2 | OUT | Regulated 5V output; requires ≥10μF ceramic capacitor to GND for stability |
| 3 | SET | Feedback input; tied to GND for fixed 5V mode; connects to resistor divider for adjustable outputs |
| 4 | PFO | Active-low open-drain power-fail output; asserts when PFI < 1.231V (e.g., battery sag) |
| 5 | CSWT | Watchdog timeout adjust; connect to OUT for fixed 280ms timeout or add capacitor for adjustment |
| 6 | CSRT | Reset timeout adjust; connect to OUT for fixed 3.125ms timeout or add capacitor for adjustment |
| 7 | GND | Analog/digital ground reference; connects to EP for thermal path |
| 8 | RESET | Active-low push-pull reset output; drives µP reset pin directly without pull-up |
| 11 | WDI | Watchdog input; requires edge transition within timeout period to prevent reset assertion |
| 12 | HOLD | Active-low latch control; forces regulator ON when low, even if ENABLE goes low |
| 16 | PFI | Power-fail comparator input; use resistive divider to set custom undervoltage detection threshold |
| 17,18 | IN | Main regulator input; bypass with 1μF ceramic capacitor to GND near pins |
| 19 | GATEP | pFET gate driver; sinks current to turn on external p-channel MOSFET for reverse-battery protection |
| 20 | ENABLE | Active-high enable; pulled down internally (0.5μA); driven by ignition switch signal |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 68μA enables >1-year battery standby in always-on automotive modules |
| Integrated reverse-battery protection driver | GATEP pin eliminates need for lossy series diode, improving efficiency and thermal margin |
| Self-holding ignition interface | HOLD + ENABLE combination allows ignition-key-triggered latching without external logic or relays |
| Adjustable supervisory timing | CSRT and CSWT pins support capacitor-based tuning of reset and watchdog timeouts for system-specific timing |
| AEC-Q100 Grade-0 qualification | Validated for -40°C to +125°C operation with lifetime reliability testing per automotive standards |
| Thermal shutdown with hysteresis | 165°C trip point with 20°C hysteresis prevents thermal cycling and ensures safe recovery |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6795TPSD2/V+ | Same 5V output but 3.125ms fixed reset timeout (D2) vs. 3.125ms (D1); automotive-grade (/V+) and lead-free (+) | Targeted specifically for AEC-Q100-compliant designs requiring traceable automotive qualification | Select MAX6795TPVD1+T for industrial or non-automotive high-reliability use; choose MAX6795TPSD2/V+ when full automotive qualification documentation is required. |
| TLV70750PDQNR | Lower voltage range (2.5V–5.5V), 300mA, 25μA IQ, SOT-23-5 - lacks watchdog, RESET, HOLD, or high-voltage capability | Suitable only for post-regulated 5V rails in non-automotive embedded systems with benign supply conditions | Use TLV70750PDQNR only in low-voltage, non-safety-critical applications where supervisory features and 72V tolerance are unnecessary. |
Compared with MAX6795TPSD2/V+, MAX6795TPVD1+T offers identical electrical performance but without formal AEC-Q100 certification; compared with TLV70750PDQNR, it provides full automotive-grade supervision, reverse-battery protection, and 72V operation - making it irreplaceable in primary automotive power domains.

FAQ
What is the output voltage configuration of the MAX6795TPVD1+T?
The MAX6795TPVD1+T is factory-configured for fixed 5.0V output, as indicated by the "V" in the suffix (per Maxim's ordering guide: V = 5.0V). It does not require external feedback resistors - SET is internally connected to GND. This configuration ensures ±2.5% output accuracy over -40°C to +125°C and load currents up to 300mA, making it ideal for powering automotive MCUs and sensors without design-in calibration.
Does the MAX6795TPVD1+T support reverse-battery protection?
Yes, the MAX6795TPVD1+T supports reverse-battery protection via its GATEP pin, which drives the gate of an external p-channel MOSFET. When battery polarity is reversed, the IC sinks current from GATEP to turn off the pFET, blocking reverse current flow. This eliminates the power loss and heat generation of traditional series diodes, preserving efficiency and thermal headroom in compact automotive modules using the MAX6795TPVD1+T.
How does the HOLD function operate in the MAX6795TPVD1+T?
The HOLD input in the MAX6795TPVD1+T enables self-holding behavior: when ENABLE is asserted high to start regulation, pulling HOLD low thereafter keeps the regulator ON even if ENABLE returns low - mimicking ignition-switch latching. Releasing HOLD (letting it float or pulling high) shuts down the output. This eliminates external latch circuitry and simplifies wiring in automotive applications where the MAX6795TPVD1+T powers modules that must remain active after key-off for defined durations.
What watchdog timeout options are available on the MAX6795TPVD1+T?
The MAX6795TPVD1+T offers a fixed 280ms minimum watchdog timeout period (tWD2) when CSWT is connected to OUT. It does not support the windowed watchdog or selectable fast/slow modes found in MAX6791/MAX6792. The watchdog can be fully disabled by driving WD-DIS low. This makes the MAX6795TPVD1+T suitable for applications needing simple timeout supervision without complex windowing logic - a key distinction from other members of the MAX6791–MAX6796 family.
Is the MAX6795TPVD1+T qualified to AEC-Q100 standards?
No, the MAX6795TPVD1+T is not AEC-Q100 qualified. Its suffix lacks the "/V" designation used in automotive-grade variants like MAX6795TPLD2/V+ or MAX6795TPSD2/V+. While it shares the same die, package, and -40°C to +125°C operating range, MAX6795TPVD1+T is intended for industrial, commercial, or non-safety-critical automotive subsystems where formal AEC-Q100 certification is not mandated. For certified applications, select the /V+ variants instead of MAX6795TPVD1+T.
