Product details
Overview
The MAX6796TPYD0+T 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 requiring robust operation across 5V–72V input and -40°C to +125°C ambient. It delivers up to 300mA at fixed 1.8V output, features 68μA quiescent current, 420mV typical dropout at 100mA, and AEC-Q100-qualified thermal protection.
For engineers reviewing the MAX6796TPYD0+T datasheet, MAX6796TPYD0+T pinout, MAX6796TPYD0+T application, or MAX6796TPYD0+T equivalent, key selection criteria include its 1.8V preset output with 87.5% reset threshold, D0 (35μs) reset timeout, TQFN-20EP package with exposed pad, and dual-mode watchdog disable capability via WD-DIS pin.
Technical Context
The MAX6796TPYD0+T implements a high-voltage pFET-based LDO architecture with internal feedback loop referenced to a precision 1.231V bandgap. Its RESET output asserts low when OUT drops below 87.5% of nominal (1.575V for 1.8V output) and remains low for a fixed 35μs timeout after recovery - no external capacitor required on CSRT.
Watchdog supervision uses a fixed 280ms minimum timeout (CSWT tied to OUT), configurable via WD-DIS pin; the device also integrates a dedicated power-fail comparator (PFI threshold = 1.231V ±0.032V) and reverse-battery protection drive (GATEP) capable of controlling an external p-channel MOSFET.
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 1.8V ±2.5% - preset at factory; no external resistor network needed |
| Max Output Current | 300mA continuous - supports microcontroller core rails and CAN transceivers |
| Quiescent Current | 68μA typical - enables always-on battery monitoring in sleep mode |
| Dropout Voltage | 420mV typ @ 100mA - ensures regulation down to VIN = 2.22V for 1.8V output |
| Reset Threshold | 87.5% of VOUT (1.575V) - precise brownout detection aligned to 1.8V logic supply |
| Reset Timeout | 35μs fixed - eliminates need for external timing capacitor; fast recovery for real-time systems |
Pinout & Package
MAX6796TPYD0+T is housed in a thermally enhanced 5mm × 5mm, 20-pin TQFN package with exposed pad (EP), rated for 2.7W power dissipation and specified from -40°C to +125°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1,2 | OUT | Regulator output (1.8V); requires ≥10μF ceramic capacitor to GND for stability |
| 3 | SET | Feedback input; tied to GND internally for 1.8V preset - not user-adjustable on this variant |
| 4 | PFO | Open-drain power-fail output; asserts low when PFI < 1.231V - used for early battery warning |
| 5 | CSWT | Watchdog timeout adjust; connected to OUT for fixed 280ms timeout - no external cap needed |
| 6 | CSRT | Reset timeout adjust; connected to OUT for fixed 35μs timeout - eliminates timing component |
| 7 | GND | Analog/digital ground reference; must be connected to PCB ground plane under EP |
| 8 | RESET | Active-low push-pull reset output; drives µP reset pin directly without pull-up |
| 11 | WDI | Watchdog input; rising/falling edge must occur within 280ms to prevent reset assertion |
| 12 | HOLD | Active-low hold control; forces regulator ON even after ENABLE goes low - enables self-hold circuits |
| 16 | PFI | Power-fail comparator input; connect to resistive divider from battery to set custom undervoltage threshold |
| 17,18 | IN | Main regulator input; bypass with 1μF ceramic capacitor to GND near pins |
| 19 | GATEP | pFET gate driver; controls external high-side p-MOSFET for reverse-battery protection |
| 20 | ENABLE | Active-high enable; pulled down internally (0.5μA sink) - driven by ignition signal in automotive |
| EP | Exposed Pad | Internally connected to GND; soldered to PCB ground plane for thermal and EMI performance |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator with supervisory functions applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6795TPYD0+T | Identical pinout, specs, and features - differs only in dual-output vs. single-output family designation; MAX6795 is single-output variant like MAX6796 but lacks Y-coded 1.8V option in same ordering suffix | Same 1.8V/300mA/68μA spec; however, MAX6795TPYD0+T is not listed in Maxim's official ordering guide for Y (1.8V) + D0 configuration - MAX6796TPYD0+T is the confirmed valid part | Select MAX6796TPYD0+T for guaranteed 1.8V/D0 configuration; MAX6795 variants require verification of output voltage code mapping |
| TLV70718PDQNR | Lower input range (2.5V–5.5V), no watchdog/RESET/PFI/GATEP; 250mA max, 25μA IQ, SOT-23-5 | Suitable only for post-regulated 3.3V→1.8V conversion in non-automotive, low-voltage systems - cannot replace 72V input or supervisory functions | Use only in cost-sensitive, low-voltage, non-safety-critical applications where full MAX6796TPYD0+T feature set is unnecessary |
Compared with MAX6795TPYD0+T (unverified Y/D0 variant) and TLV70718PDQNR (low-voltage-only), the MAX6796TPYD0+T uniquely combines 72V input tolerance, AEC-Q100 qualification, integrated watchdog/RESET/PFI/GATEP, and factory-preset 1.8V/35μs functionality in one automotive-grade package.

FAQ
What output voltage does the MAX6796TPYD0+T deliver?
The MAX6796TPYD0+T delivers a factory-preset 1.8V output with ±2.5% accuracy over -40°C to +125°C. The "Y" in the part number explicitly denotes the 1.8V option, and no external feedback resistors are required - SET is internally grounded for this variant.
Does the MAX6796TPYD0+T require an external capacitor for reset timeout?
No. The MAX6796TPYD0+T uses the D0 reset timeout option, providing a fixed 35μs reset pulse width. CSRT is internally connected to OUT, eliminating the need for an external timing capacitor - simplifying layout and improving reliability.
Can the watchdog function be disabled on the MAX6796TPYD0+T?
Yes. The MAX6796TPYD0+T includes a dedicated WD-DIS pin (Pin 10). Driving WD-DIS low disables the watchdog timer entirely, allowing the device to operate as a pure regulator + RESET supervisor without periodic WDI toggling requirements.
What is the purpose of the GATEP pin on the MAX6796TPYD0+T?
The GATEP pin on the MAX6796TPYD0+T drives the gate of an external p-channel MOSFET to implement reverse-battery protection. It eliminates the power loss and heat generation of a series Schottky diode, supporting high-current (>10A) automotive inputs while maintaining low forward voltage drop.
Is the MAX6796TPYD0+T qualified for automotive use?
Yes. The MAX6796TPYD0+T is AEC-Q100 qualified (Grade 0, -40°C to +125°C) and built in an automotive-grade flow. It includes thermal shutdown (165°C), short-circuit protection, output overvoltage clamp, and 72V absolute maximum input - meeting stringent automotive reliability requirements.
