Product details
Overview
TLE7469GV52AUMA1 from Infineon Technologies is a dual-output automotive-grade low-dropout voltage regulator providing 5.0 V ±2% (215 mA) and 2.6 V ±4% (200 mA) outputs, integrated reset generator with adjustable power-on delay, window watchdog, early warning comparator, and inhibit control - designed for dual-rail microcontroller supply in body electronics and powertrain ECUs.
For engineers reviewing the TLE7469GV52AUMA1 datasheet, TLE7469GV52AUMA1 pinout, TLE7469GV52AUMA1 application, or TLE7469GV52AUMA1 equivalent, key selection criteria include output voltage pairing (5 V / 2.6 V), ultra-low quiescent current (<55 µA), AEC-Q100 qualification, thermal shutdown behavior, and PG-DSO-12 package compatibility with automotive PCB layout constraints.
Technical Context
The device integrates two independent LDO regulators with separate input pins (I1, I2) and dedicated ground paths (Pins 6 & 11 + heat slug), enabling asymmetric input sourcing and robust noise isolation. Its charge-pump-based architecture enables ultra-low quiescent current while maintaining <600 mV dropout at full load on Q1.
Reset generation monitors both Q1 and Q2 outputs simultaneously; the DT pin selects timing via connection to GND/Q1/Q2, configuring reset delay and watchdog timeout. The early warning comparator (SI/SO) supports external rail supervision with open-collector output, and the RO pin delivers an open-collector reset signal with internal 20 kΩ pull-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Q1 | 5.0 V ±2%, 215 mA max - powers MCU I/O rails with tight regulation across 6–16 V input and -40 °C to 150 °C junction temperature. |
| Output Q2 | 2.6 V ±4%, 200 mA max - supplies XC164/XC161 MCU core voltage; differential voltage |VQ1−VQ2| held within −0.5 V to 3.0 V during sequencing. |
| Quiescent Current | <55 µA typical - enables always-on body modules (e.g., door modules, seat controllers) without battery drain concerns. |
| Dropout Voltage Q1 | 300–600 mV at 215 mA - allows operation down to VI1 = 5.6 V, supporting cold-crank conditions in 12 V automotive systems. |
| Reset Function | Power-on delay adjustable via DT pin; monitors both outputs; RO is open-collector with 20 kΩ internal pull-up - eliminates need for external reset IC. |
| Watchdog | Window watchdog with WDI input - detects firmware hang by requiring periodic pulses; prevents uncontrolled MCU operation in safety-critical nodes. |
| Protection Features | Short-circuit, overload, overtemperature, reverse-current (Q1 clamped ≤5.5 V), and ESD (HBM ≥2 kV) - meets ISO 7637-2 pulse immunity requirements when properly decoupled. |
Pinout & Package
Package: PG-DSO-12 (exposed thermal pad), RoHS-compliant, AEC-Q100 qualified, 150 °C max junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (I1) | Main input supply for Q1 | Accepts 5.6–45 V; requires local 100 nF ceramic capacitor to GND for stability and transient response. |
| 2 (INH) | Inhibit control input | Active-low enable; internal pull-down; drives IC into <9 µA standby mode - used for system-level sleep/wake coordination. |
| 3 (Q1) | 5.0 V regulated output | Supplies MCU I/O domain; requires ≥1 µF output capacitor with ESR <6 Ω @ 10 kHz to maintain stability and PSRR. |
| 4 (SO) | Early warning comparator output | Open-collector; sinks current when SI voltage exceeds threshold - interfaces directly with MCU GPIO or external logic. |
| 5 (WDI) | Watchdog trigger input | Accepts CMOS-level pulses; missing or out-of-window pulses trigger reset - ensures deterministic firmware recovery. |
| 6, 11 (GND) | Ground reference and thermal path | Must connect both pins and exposed heat slug to PCB ground plane - critical for thermal performance (Rthjc = 4.4 K/W). |
| 7 (DT) | Delay timing configuration | Connect to GND/Q1/Q2 to set reset delay and watchdog timeout - enables flexible power sequencing without external components. |
| 8 (SI) | Early warning comparator input | Monitors external voltage (e.g., battery, sensor supply); threshold set internally - adds supervisory capability beyond internal rails. |
| 9 (RO) | Reset output | Open-collector reset signal with 20 kΩ internal pull-up; asserts low during power-on delay and fault conditions. |
| 10 (Q2) | 2.6 V regulated output | Supplies MCU core; same capacitor requirements as Q1; voltage differential with Q1 actively managed during ramp-up/down. |
| 12 (I2) | Input supply for Q2 | Accepts 4.2–45 V (VI1 < 8 V) or 6.0–45 V (VI1 ≥ 8 V); supports independent sourcing from Q1 input. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDOs with sequencing control | Enables safe power-up/down of 5 V I/O and 2.6 V core rails without external clamping diodes or sequencing ICs. |
| Integrated window watchdog + reset generator | Reduces BOM count by eliminating discrete reset supervisor and watchdog timer ICs in ECU designs. |
| Early warning comparator with SI/SO interface | Allows monitoring of third-party rails (e.g., sensor supply, CAN transceiver VCC) using one analog input and one GPIO. |
| Ultra-low quiescent current (<55 µA) | Supports >10-year battery life in always-on automotive modules such as keyless entry receivers and tire pressure sensors. |
| Reverse current protection on Q1 | Clamps Q1 to ≤5.5 V during reverse-battery or load-dump events - protects downstream logic without external TVS. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output automotive LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV70733PDQNR | Single 3.3 V output (200 mA), no watchdog/reset, no inhibit, SOT-23-5 package | Lacks dual-rail support, sequencing, and automotive qualification - suitable only for non-safety prototyping. | Select only for cost-sensitive non-automotive applications where 5 V/2.6 V pairing and AEC-Q100 are not required. |
| MAX16910ATP+ | Dual 5 V / 3.3 V outputs, integrated watchdog and reset, but no early warning comparator or inhibit function | Higher quiescent current (80 µA), no SI/SO supervision, and different pinout - requires PCB redesign. | Consider when 3.3 V core (not 2.6 V) is needed and early warning supervision is unnecessary. |
Compared with TLV70733PDQNR and MAX16910ATP+, the TLE7469GV52AUMA1 uniquely combines 2.6 V core output, ultra-low quiescent current, inhibit control, and SI/SO supervision - making it irreplaceable in AEC-Q100-compliant dual-rail MCU systems requiring extended battery life and functional safety features.

FAQ
What is the maximum allowable input voltage for I1 and I2?
The absolute maximum input voltage for both I1 and I2 is 45 V, with minimum ratings of −0.3 V. Operation above 45 V risks irreversible damage. The recommended operating range is 5.6–45 V for I1 and 4.2–45 V for I2 (depending on I1 voltage), per Table 3 in the datasheet.
How does the DT pin configure reset and watchdog timing?
Connecting DT to GND sets shortest reset delay (~10 ms) and watchdog timeout (~1.6 s); connecting to Q1 extends both to medium values (~50 ms / ~8 s); connecting to Q2 gives longest settings (~200 ms / ~32 s). This eliminates external timing resistors and enables software-configurable sequencing.
Can TLE7469GV52AUMA1 be used with a 3.3 V core instead of 2.6 V?
No - the GV52 suffix denotes fixed 2.6 V Q2 output. For 3.3 V core, use TLE7469GV53AUMA1, which shares identical pinout, features, and package but delivers 3.3 V ±3% on Q2. Output voltage is laser-trimmed during manufacture and not user-adjustable.
Is external capacitor required on the SO (sense output) pin?
No external capacitor is required on SO, as it is an open-collector output intended to drive logic inputs or pull-up resistors. However, a small RC filter (e.g., 10 kΩ + 100 pF) may be added if electromagnetic interference causes false triggering in noisy environments - this is application-specific and not specified in the datasheet.
