Product details
Overview
MAX8569BETT30-T from Maxim Integrated is a fixed-output 3.0V, 200mA synchronous boost regulator in a 6-pin TDFN package, operating from 1.5V to 5.5V input. It integrates an internal n-channel/p-channel MOSFET pair, synchronous rectifier, and power-on reset (RST) output. Designed for battery-powered portable electronics, it delivers >90% efficiency at 40mA load with 7µA quiescent current and supports backup power routing during shutdown.
For engineers reviewing the MAX8569BETT30-T datasheet, MAX8569BETT30-T pinout, MAX8569BETT30-T application, or MAX8569BETT30-T equivalent, key selection criteria include its fixed 3.0V output tolerance (±2.5%), RST open-drain reset threshold (90% of VOUT), shutdown current <1µA, and TDFN-6 thermal performance (1454mW at +70°C).
Technical Context
The MAX8569BETT30-T uses a current-limited, oscillator-free control scheme where switch on-time terminates either at 750mA n-channel current limit or 5µs maximum on-time. Its synchronous rectification eliminates external Schottky diode requirements and enables BATT-to-OUT conduction during shutdown via internal p-channel MOSFET.
It features dual threshold detection: SHDN input triggers shutdown at 1.228V (with 100mV hysteresis), while RST asserts low when VOUT falls below 90% of 3.0V (i.e., 2.7V). Feedback regulation is internal-no external resistor divider required-unlike the adjustable MAX8569A variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±2.5% (2.925V–3.075V) over -40°C to +85°C - ensures stable logic supply for 3.0V microcontrollers and sensors. |
| Max Output Current | 200mA at VBATT = 2.0V, VOUT = 3.0V - sufficient for powering small displays, RF modules, or sensor interfaces. |
| Quiescent Current | 7µA typical - minimizes battery drain in always-on monitoring circuits like real-time clocks or wake-up controllers. |
| Shutdown Current | <1µA - enables multi-year operation on coin cells when paired with ultra-low-power loads. |
| Efficiency | 90% typical at 40mA, VBATT = 2.0V - reduces thermal stress and extends runtime in space-constrained handheld devices. |
| RST Threshold | 90% of nominal VOUT (2.7V) - provides clean power-good signaling for microprocessor reset sequencing. |
| Input Voltage Range | 1.5V to 5.5V - supports single Li+ (3.0–4.2V), two alkaline/NiMH (2.0–3.2V), or USB-supplied systems. |
Pinout & Package
MAX8569BETT30-T is housed in a 3mm × 3mm × 0.8mm exposed-pad TDFN-6 package (package code T633-1), with EP (exposed paddle) thermally connected to PCB ground plane for enhanced thermal dissipation (1454mW max power at +70°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - SHDN | Active-low enable input | Drives IC into sub-1µA shutdown; doubles as low-battery cutoff detector (1.228V threshold). |
| 2 - BATT | Battery input supply | Accepts 1.5V–5.5V source; internally connected to OUT during shutdown for backup power routing. |
| 3 - GND | Analog/digital ground reference | Must be tied directly to PCB ground plane; critical for noise immunity and thermal performance via EP connection. |
| 4 - LX | Switch node | Connects to inductor; carries pulsed current up to 750mA peak; tied to OUT during shutdown. |
| 5 - OUT | Regulated output | Delivers fixed 3.0V; supplies internal bias and serves as RST pull-up reference; bypassed with ≥10µF ceramic cap. |
| 6 - RST | Open-drain reset output | Pulls low when VOUT < 2.7V; high-impedance otherwise - requires external 100kΩ–1MΩ pull-up to OUT for logic-level reset signal. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Eliminates external Schottky diode, reducing BOM count, board area, and forward-voltage losses. |
| BATT-to-OUT path in shutdown | Enables battery-backed RTC, SRAM, or MCU retention without added diodes or discrete switches. |
| Integrated RST output | Provides system-level power-good indication with precise 90% VOUT threshold - no external supervisor IC needed. |
| Ultra-low quiescent current | 7µA operating / <1µA shutdown - preserves battery life in intermittent-sensing applications (e.g., IoT endpoints). |
| Current-limited control architecture | Self-adjusting switching frequency based on load and input voltage - avoids audible noise and simplifies EMI filtering. |

FAQ
What is the output voltage tolerance of the MAX8569BETT30-T over temperature and load?
The MAX8569BETT30-T delivers a fixed 3.0V output with ±2.5% tolerance (2.925V to 3.075V) across the full -40°C to +85°C operating range and 1mA–200mA load. This specification is guaranteed by design and verified per Maxim's production test flow, ensuring compatibility with 3.0V logic interfaces and precision analog circuitry without external trimming.
Does the MAX8569BETT30-T require external feedback resistors to set the output voltage?
No, the MAX8569BETT30-T does not require external feedback resistors. Its output is factory-trimmed to 3.0V and internally regulated - unlike the adjustable MAX8569A variant. The FB pin is unused in this version; pin 6 functions exclusively as the RST output, eliminating layout complexity and resistor tolerance errors associated with external dividers.
How does the RST output of the MAX8569BETT30-T behave during power-up and fault conditions?
The RST output of the MAX8569BETT30-T is an open-drain signal that remains high-impedance until VOUT reaches 90% of 3.0V (2.7V), then pulls low if VOUT drops below that threshold. During shutdown (SHDN low), RST goes high-impedance regardless of VOUT. A 100kΩ–1MΩ pull-up to OUT is required to generate a valid logic-high reset signal for microcontrollers.
Can the MAX8569BETT30-T operate from a single 1.5V alkaline cell?
Yes, the MAX8569BETT30-T starts up reliably from 1.5V input (typical startup voltage is 1.24V at -40°C to +85°C) and sustains regulation down to ~1.6V under light load. This enables use with single alkaline or NiMH cells, supporting applications like remote sensors or wearables where minimal cell count is essential for size and cost constraints.
What thermal considerations apply to the MAX8569BETT30-T in its TDFN-6 package?
The MAX8569BETT30-T in TDFN-6 (T633-1) has a maximum continuous power dissipation of 1454mW at +70°C, derating at 18.2mW/°C above that. To maintain reliability, the exposed paddle (EP) must be soldered to a solid PCB ground plane. Thermal impedance drops significantly with ≥2cm² copper area beneath EP, enabling full 200mA output in ambient temperatures up to +65°C with proper layout.
