Product details
Overview
MAX6796TPMD2+ from Maxim Integrated is a single-output, high-voltage linear regulator with integrated supervisory functions (RESET, watchdog, power-fail detection) designed for automotive systems. It operates from 5V to 72V input, delivers up to 300mA output current, features 68μA quiescent current, and provides a fixed 5V output with 87.5% reset threshold and 12.5ms reset timeout period (D2 code). It is used in engine control units (ECUs) and body control modules requiring robust voltage regulation under load-dump conditions.
For engineers reviewing the MAX6796TPMD2+ datasheet, MAX6796TPMD2+ pinout, MAX6796TPMD2+ application, or MAX6796TPMD2+ equivalent, key selection criteria include its AEC-Q100-qualified 5mm × 5mm TQFN package, -40°C to +125°C operation, dual-mode watchdog disable capability, thermal/short-circuit protection, and compatibility with reverse-battery pFET gate drive via GATEP pin.
Technical Context
The MAX6796TPMD2+ implements a single high-side linear regulator with internal pass transistor, supporting fixed 5V output (M suffix) and active-low RESET with push-pull or open-drain configuration. Its supervisory block integrates a capacitor-adjustable reset timeout (CSRT = OUT), fixed 280ms watchdog timeout (CSWT = OUT), and programmable watchdog disable via WD-DIS pin.
It features ENABLE and HOLD inputs enabling self-holding circuitry without external components: once enabled, pulling HOLD low sustains regulation even after ENABLE returns low; releasing HOLD shuts down the output. The device also includes PFI/PFO comparator for battery voltage monitoring and GATEP-driven pFET control for reverse-battery protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 5V to 72V - withstands automotive load-dump transients without external clamping |
| Output Current | 300mA - sufficient to power microcontrollers, CAN transceivers, and sensor interfaces |
| Quiescent Current | 68μA - enables always-on functionality in battery-sensitive automotive modules |
| Reset Threshold | 87.5% of VOUT (4.375V at 5V output) - ensures reliable brownout detection before MCU malfunction |
| Reset Timeout | 12.5ms (D2 code) - meets automotive reset timing requirements for deterministic boot recovery |
| Watchdog Timeout | 280ms (fixed, CSWT = OUT) - provides fail-safe supervision for safety-critical firmware execution |
| 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 in compact layouts |
Pinout & Package
The MAX6796TPMD2+ 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 suppression.
| 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; grounded for 5V preset output (M code), or used with 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; tied to OUT for fixed 280ms timeout (D2 variant uses internal setting) |
| 6 | CSRT | Reset timeout adjust; tied to OUT for fixed 12.5ms timeout (D2 code) |
| 7 | GND | Analog/digital ground reference; connects to EP for thermal path |
| 8 | RESET | Active-low push-pull reset output; drives MCU reset pin directly without pull-up |
| 11 | WDI | Watchdog input; requires periodic edge transition within 280ms to prevent reset assertion |
| 12 | HOLD | Active-low hold enable; sustains regulation after ENABLE goes low - enables ignition-key self-hold logic |
| 16 | PFI | Power-fail comparator input; sets battery undervoltage threshold via external resistor divider |
| 17,18 | IN | Main regulator input; bypassed with 1μF ceramic capacitor to GND |
| 19 | GATEP | pFET gate driver; controls external high-side p-channel MOSFET for reverse-battery protection |
| 20 | ENABLE | Active-high enable; internally pulled down (0.5μA sink); driven by ignition switch or system controller |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 68μA at no load - extends battery life in always-on automotive modules |
| Integrated reverse-battery protection | GATEP pin drives external pFET - eliminates series diode drop and heat generation |
| Self-holding circuit support | HOLD + ENABLE logic enables ignition-key latching without external latch IC or discrete components |
| Dual-mode watchdog disable | WD-DIS pin or WDS0/WDS1 combination allows hardware-based watchdog deactivation during debug or safe mode |
| Thermal and short-circuit protection | 165°C shutdown with 20°C hysteresis - prevents damage during overload or ambient extremes |
| AEC-Q100 qualification | Qualified per AEC-Q100 Rev H Grade 0 - validated for under-hood automotive deployment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage supervisory regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6795TPMD2+ | Same pinout, identical electrical specs, but lacks AEC-Q100 qualification; rated for industrial temp only (-40°C to +105°C) | Suitable for non-automotive industrial control or test equipment where automotive qualification is not required | Select MAX6795TPMD2+ only if AEC-Q100 is unnecessary and cost sensitivity outweighs extended temperature margin |
| TLV70750PDQNR | Lower input range (2.5V–5.5V), no watchdog or RESET, 200mA output, SOT-23-5 package | Limited to post-regulated 5V domains; cannot replace MAX6796TPMD2+ in direct battery-fed applications | Use TLV70750PDQNR only as secondary LDO downstream of a buck converter - not a functional substitute for primary battery-supervised regulation |
Compared with MAX6795TPMD2+, the MAX6796TPMD2+ adds AEC-Q100 qualification and extended +125°C operation for under-hood use; compared with TLV70750PDQNR, it provides full battery-direct operation, integrated supervision, and 300mA drive - making it uniquely suited for automotive primary regulation.

FAQ
What output voltage does the MAX6796TPMD2+ provide?
The MAX6796TPMD2+ provides a fixed 5V output. The "M" in the part number denotes the 5V preset option, and the D2 suffix specifies an 87.5% reset threshold (4.375V) with a 12.5ms reset timeout period. It does not support adjustable output - that functionality requires the "A" or "B" suffix variants with external SET resistor dividers.
Does the MAX6796TPMD2+ include watchdog functionality?
Yes, the MAX6796TPMD2+ includes a configurable watchdog timer with a fixed 280ms timeout period (when CSWT is tied to OUT). It monitors the WDI pin for valid edges and asserts RESET if no transition occurs within the timeout window. The watchdog can be disabled using the WD-DIS pin, providing flexibility during firmware development or safe-mode operation.
How does the HOLD pin function on the MAX6796TPMD2+?
The HOLD pin on the MAX6796TPMD2+ enables self-holding behavior: when pulled low after initial enable, it keeps the regulator ON even if ENABLE returns low. This allows ignition-switch-driven latching without external components. Releasing HOLD (letting it float or pulling high) shuts down the output. HOLD is internally pulled up to OUT with a 2µA current source.
Is the MAX6796TPMD2+ qualified for automotive use?
Yes, the MAX6796TPMD2+ is AEC-Q100 qualified (Grade 0, -40°C to +125°C) and designed for automotive applications including engine control, body electronics, and ADAS. Its 5V–72V input range, load-dump tolerance, and integrated reverse-battery protection via GATEP make it suitable for direct battery connection in harsh vehicle environments.
What package type and thermal performance does the MAX6796TPMD2+ offer?
The MAX6796TPMD2+ uses a 20-pin TQFN-EP package (5mm × 5mm) with exposed pad. It dissipates up to 2.7W continuously and supports operation at +125°C ambient, enabled by low thermal resistance between die and PCB ground plane through the soldered EP. Derating begins above +70°C at 33.3mW/°C.
