Product details
Overview
MAX6796TPVD0+ from Maxim Integrated is a single-output, ultra-low-quiescent-current linear regulator with integrated supervisory functions (RESET, watchdog, power-fail comparator, and hold control), designed for automotive systems operating from 5V to 72V input. It delivers up to 300mA output current, features 68μA quiescent current, fixed 5V output (D0 suffix), and AEC-Q100-qualified operation from −40°C to +125°C.
For engineers reviewing the MAX6796TPVD0+ datasheet, MAX6796TPVD0+ pinout, MAX6796TPVD0+ application, or MAX6796TPVD0+ equivalent, key selection considerations include its 5V fixed output with 92.5% reset threshold, 20-pin TQFN package with exposed pad, 35μs reset assertion delay, capacitor-adjustable reset timeout (D0 = 35μs fixed), and watchdog disable capability via WD-DIS pin.
Technical Context
The MAX6796TPVD0+ implements a high-voltage pFET-based LDO architecture with thermal and short-circuit protection, supporting continuous operation under load-dump conditions. Its RESET output is push-pull active-low with fixed 92.5% threshold relative to VOUT and 35μs assertion delay, while the watchdog timer offers fixed 280ms timeout (CSWT tied to OUT) and can be disabled via WD-DIS.
It integrates a precision 1.231V PFI comparator for battery monitoring, HOLD functionality enabling self-holding without external components, and GATEP drive for reverse-battery pFET protection. The device uses internal SET feedback reference (124mV rising / 62mV falling) for adjustable output configurations - though unused in this D0-fixed 5V variant.
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% - preset by D0 suffix; no external resistor required |
| Max Output Current | 300mA - sufficient for MCU core rails and CAN transceivers in body control modules |
| Quiescent Current | 68μA typical - enables always-on functionality in low-power automotive sleep modes |
| Reset Threshold | 4.625V (92.5% of 5V) - asserts RESET when VOUT drops below this level |
| Reset Timeout | 35μs fixed - fast response for brownout detection during ignition cycling |
| Operating Temp | −40°C to +125°C - fully specified for under-hood automotive environments |
Pinout & Package
MAX6796TPVD0+ is housed in a 5mm × 5mm, 20-pin thermally enhanced TQFN-EP package (exposed pad connected to GND). The package supports up to 2.7W power dissipation and is qualified per AEC-Q100 Grade 0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | OUT | Regulator output (5V fixed); requires ≥10μF ceramic capacitor to GND for stability |
| 3 | SET | Feedback input; tied to GND internally for D0 fixed-output configuration |
| 4 | PFO | Active-low open-drain power-fail output; asserts when PFI < 1.231V |
| 5 | CSWT | Watchdog timeout adjust; tied to OUT for fixed 280ms timeout (D0 variant) |
| 6 | CSRT | Reset timeout adjust; tied to OUT for fixed 35μs timeout (D0 variant) |
| 7 | GND | Analog/digital ground reference; connects to exposed pad for thermal conduction |
| 8 | RESET | Push-pull active-low reset output; drives µP reset pin directly without pull-up |
| 11 | WDI | Watchdog input; toggling required within timeout period to prevent reset assertion |
| 12 | HOLD | Active-low hold control; forces regulator ON even after ENABLE goes low |
| 16 | PFI | Power-fail comparator input; set via resistive divider to monitor battery or pre-reg voltage |
| 17, 18 | IN | Main regulator input; bypassed with 1μF ceramic capacitor to GND |
| 19 | GATEP | pFET gate driver; enables reverse-battery protection using external p-channel MOSFET |
| 20 | ENABLE | Active-high enable; pulled down internally (0.5μA sink); controls regulator startup |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ (68μA) | Enables >1-year battery standby life in always-on automotive modules (e.g., telematics, alarm systems) |
| 72V Input Tolerance | Eliminates need for external TVS or overvoltage clamping in 24V truck/bus applications |
| Integrated HOLD Function | Permits ignition-key-triggered latching without external latch circuitry or microcontroller intervention |
| Push-Pull RESET Output | Drives standard µP reset inputs directly - no external pull-up resistor required |
| WD-DIS Pin Control | Hardware-level watchdog disable allows safe firmware update windows without reset interference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage automotive regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6795TPVD0+ | Same electrical specs and pinout; differs only in tape-and-reel packaging (2.5k vs. 1k reel) | No functional difference; identical use in production and prototyping | Select MAX6795TPVD0+ for smaller-volume sampling or evaluation board integration |
| TLV70750PDQNR | Lower input range (2.5V–5.5V), 200mA max, no watchdog/RESET/PFI; SOT-23-5 package | Not suitable for automotive main power; limited to post-regulated 5V rails in infotainment head units | Use only in non-safety-critical, low-voltage auxiliary circuits where supervision is handled externally |
Compared with MAX6795TPVD0+, the MAX6796TPVD0+ offers identical regulation and supervision but is optimized for volume production with standard tape-and-reel packaging; versus TLV70750PDQNR, it provides full automotive-grade high-voltage operation, integrated safety monitoring, and thermal robustness - essential for primary ECU power domains.

FAQ
What output voltage does the MAX6796TPVD0+ provide?
The MAX6796TPVD0+ provides a fixed 5.0V output voltage, as indicated by the "D0" suffix in the part number. This is factory-trimmed to ±2.5% over temperature and load, eliminating the need for external feedback resistors. The device does not support adjustable output in this variant - SET is internally grounded.
Does the MAX6796TPVD0+ include watchdog functionality, and how is it configured?
Yes, the MAX6796TPVD0+ includes a configurable watchdog timer with fixed 280ms timeout (min), enabled by connecting CSWT to OUT. It can be disabled via the WD-DIS pin (drive low). Unlike MAX6791/MAX6792, it does not support windowed watchdog mode - only single-timer operation with fast-disable capability.
What is the purpose of the HOLD pin on the MAX6796TPVD0+?
The HOLD pin on the MAX6796TPVD0+ enables self-holding behavior: once ENABLE is asserted and the regulator starts, pulling HOLD low maintains regulation even if ENABLE returns low. Releasing HOLD shuts down the output. This allows ignition-switch-triggered latching without external logic - a key feature for automotive power sequencing.
Can the MAX6796TPVD0+ be used in reverse-battery protection circuits?
Yes, the MAX6796TPVD0+ integrates reverse-battery protection via its GATEP pin, which drives the gate of an external p-channel MOSFET. When reverse polarity is applied, GATEP disables the FET, blocking current flow. This eliminates the power loss and heat generation of series diodes - critical for high-efficiency automotive power designs.
Is the MAX6796TPVD0+ AEC-Q100 qualified?
Yes, the MAX6796TPVD0+ is AEC-Q100 qualified (Grade 0, −40°C to +125°C), with full characterization across temperature, voltage, and lifetime stress tests. This qualification confirms suitability for automotive powertrain, chassis, and safety-critical ECUs where reliability under harsh environmental conditions is mandatory.
