Product details
Overview
MAX6769TALD3+ from Maxim Integrated is an automotive-grade micropower linear regulator with integrated supervisor, delivering 100mA output at 5.0V (fixed), operating from 4V to 72V input, featuring adjustable reset threshold via RESETIN pin, 50ms fixed reset timeout (D3 suffix), and active-low open-drain RESET output - used in always-on body control modules for reliable microcontroller power and reset management.
For engineers reviewing the MAX6769TALD3+ datasheet, MAX6769TALD3+ pinout, MAX6769TALD3+ application, or MAX6769TALD3+ equivalent, key selection criteria include its -40°C to +125°C automotive qualification, 31µA quiescent current, 620mV dropout at 100mA/5V, RESETIN-adjustable reset threshold, and TDFN-6EP package thermal performance under high ambient conditions.
Technical Context
The MAX6769TALD3+ implements a single-enable (ENABLE) linear regulator architecture with external reset threshold configuration via RESETIN pin and resistor divider, supporting brownout detection independent of VOUT. Its supervisor block asserts an open-drain RESET signal when RESETIN falls below a voltage derived from internal 1.147V reference (L/T/Z/W family), with fixed 50ms timeout set by D3 suffix.
It integrates overtemperature shutdown (160°C trip, 20°C hysteresis) and short-circuit protection, operates without external compensation, and uses a thermally enhanced 3mm × 3mm TDFN-EP package rated for 1.951W dissipation at TA ≤ +70°C - enabling continuous operation in engine bay or junction box environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V to 72V - supports full automotive battery range including cold-crank (4V) and load-dump (72V) transients without external protection. |
| Output Voltage | Fixed 5.0V ±2.5% - tightly regulated for MCU core/logic supply with 1.5% load regulation (1–100mA). |
| Quiescent Current | 31µA typical - enables >10-year battery life in always-on modules such as door modules or telematics. |
| Dropout Voltage | 620mV at 100mA - ensures regulation down to VIN = 5.62V, critical during low-battery cranking. |
| Reset Timeout | 50ms typical (D3) - meets µP reset timing requirements for deterministic boot after power recovery. |
| RESET Threshold Source | Adjustable via RESETIN pin - allows monitoring of auxiliary rail (e.g., 3.3V domain) using external resistive divider. |
| Operating Temperature | -40°C to +125°C - fully specified for under-hood and chassis-mounted automotive applications. |
Pinout & Package
Package: 6-pin TDFN-EP (3mm × 3mm, exposed pad), thermally optimized for PCB copper area mounting; dissipation up to 1.951W at TA ≤ +70°C with proper layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Regulator Input | Bypassed to GND with ≥0.1µF capacitor; withstands 80V absolute max - handles load dump without clamping diodes. |
| 2 GND | Ground Reference | Power and signal ground; EP (exposed pad) must be soldered to PCB ground plane for thermal and EMI performance. |
| 3 ENABLE | Active-High Enable | Drives high to activate regulator; internally pulled down (0.6µA sink) - compatible with 3.3V/5V logic without level shift. |
| 4 RESET | Active-Low Open-Drain Reset Output | Sinks ≥3.2mA at 0.4V; requires external pullup - interfaces directly with µP reset input (e.g., ARM Cortex-M, Renesas RH850). |
| 5 TIMEOUT | Reset Timeout Adjustment | Connected to OUT for fixed 50ms timeout (D3); floating or misconnected causes undefined behavior. |
| 6 OUT | Regulated Output | 5.0V output; bypassed with ≥10µF/ESR <0.5Ω capacitor - ensures stability across -40°C to +125°C. |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable Reset Monitoring | RESETIN pin accepts external voltage divider to set custom reset threshold (e.g., monitor 3.3V rail at 2.97V) - eliminates need for discrete supervisor IC. |
| Automotive Thermal Robustness | 160°C thermal shutdown with 20°C hysteresis and 3mm × 3mm TDFN-EP package - sustains operation in 105°C ambient engine bay with 1.951W dissipation capability. |
| Ultra-Low Quiescent Current | 31µA typical supply current - reduces parasitic drain to <10µA/hour, meeting ISO 16750-2 Class D (sleep mode) requirements. |
| High-Voltage Input Tolerance | Withstands 80V absolute max on IN pin - eliminates need for external TVS in most 12V/24V automotive systems. |
| Integrated Protection | Overtemperature, short-circuit, and output overvoltage (1.1×VOUT) protection - prevents latch-up or damage during fault conditions without external circuitry. |
Applications
| Body Control Module (BCM) | Telematics Control Unit (TCU) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive linear regulator with supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6765TALD3+ | No RESETIN pin; fixed VOUT and fixed reset threshold tied to VOUT (4.625V for 5V version). | Suitable only when reset monitoring must track VOUT directly - not for auxiliary rail supervision. | Select MAX6765TALD3+ if system requires simpler, lower-cost reset tied solely to 5V output. |
| TLV70750PDQNR | Lower input range (2.5V–5.5V), no supervisor, no RESETIN, 200mA output, SOT-23-5 package. | Limited to infotainment or interior modules with stable 5V input - cannot replace in 12V/24V automotive main rail. | Choose TLV70750PDQNR only for non-automotive, low-voltage, cost-sensitive applications without supervision needs. |
Compared with MAX6765TALD3+, MAX6769TALD3+ adds RESETIN-based flexible reset monitoring but shares identical 5V output, 50ms timeout, and TDFN-6EP package; versus TLV70750PDQNR, it provides full automotive voltage range, integrated supervisor, and thermal robustness - making it irreplaceable in under-hood or chassis-mounted designs.

FAQ
What is the function of the RESETIN pin on the MAX6769TALD3+?
The RESETIN pin on the MAX6769TALD3+ enables adjustable reset threshold monitoring of an external voltage rail (e.g., 3.3V domain) using a resistive divider. It references an internal 1.147V threshold (L/T/Z/W family), allowing precise brownout detection independent of the 5.0V output - a key differentiator from fixed-threshold variants like MAX6765TALD3+.
Does the MAX6769TALD3+ include watchdog timer functionality?
No, the MAX6769TALD3+ does not include a watchdog timer. Watchdog functionality is exclusive to MAX6773/MAX6774 (1.6s timeout) and MAX6773B/MAX6774B (50ms timeout) variants. The MAX6769TALD3+ belongs to the ENABLE-only subgroup (MAX6769/MAX6770) and provides only reset supervision via RESETIN and fixed 50ms timeout.
What is the maximum allowable power dissipation for MAX6769TALD3+ at 105°C ambient?
At 105°C ambient, the MAX6769TALD3+ (TDFN-6EP) has a derated power dissipation of 1.9W − (0.0244W/°C × (105°C − 70°C)) = 1.9W − 0.854W = 1.046W. This limits usable output current based on (VIN − VOUT) × IOUT < 1.046W - e.g., at VIN = 14V and VOUT = 5V, max IOUT ≈ 116mA, but device current limit caps it at 100mA.
Can the MAX6769TALD3+ be used with a 24V truck battery system?
Yes, the MAX6769TALD3+ is fully qualified for 24V commercial vehicle systems: its 4V–72V input range covers 24V nominal, cold-crank (down to ~14V), and load-dump transients (up to 72V). Its AEC-Q100 Grade 0 qualification (-40°C to +125°C) and 80V absolute maximum rating on IN ensure robust operation in heavy-duty applications.
What capacitor value is required on the TIMEOUT pin for the MAX6769TALD3+ to achieve its specified 50ms reset timeout?
The MAX6769TALD3+ uses the D3 suffix, indicating a fixed 50ms reset timeout achieved by connecting the TIMEOUT pin directly to the OUT pin - no external capacitor is required or recommended. Adding a capacitor to TIMEOUT would override the factory-trimmed timeout and result in undefined timing behavior.
