Product details
Overview
MAX6775XKB+T from Maxim Integrated is a single-channel, fixed-hysteresis (5%) battery monitor IC in 5-pin SC70 package, designed for low-power detection of falling battery voltage in Li+ and multicell alkaline/NiMH/NiCd systems. It features 1.0% threshold accuracy over -40°C to +85°C, 3µA supply current, push-pull active-low output, and guaranteed valid logic state down to VBATT = 1V.
For engineers reviewing the MAX6775XKB+T datasheet, MAX6775XKB+T pinout, MAX6775XKB+T application, or MAX6775XKB+T equivalent, key selection considerations include its factory-set 5% hysteresis, SC70 footprint compatibility, 1.1609V falling threshold, immunity to short battery transients, and support for direct interface with microprocessor reset or power-management circuitry.
Technical Context
The MAX6775XKB+T implements a precision bandgap reference with comparator-based threshold detection and internal hysteresis control. Its fixed 5% hysteresis is trimmed at factory and referenced to an internal 1.222V rising threshold, yielding a confirmed 1.1609V falling threshold (VLBIF) and 61.1mV hysteresis voltage (VHYST).
It operates from 1.2V to 5.5V supply, delivers sub-10µs propagation delay, guarantees output validity down to 1V supply, and maintains <±5nA input leakage across temperature - enabling high-impedance resistive divider use without significant error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2V to 5.5V - supports operation down to depleted single-cell Li+ or NiMH states |
| Falling Threshold (VLBIF) | 1.1609V - factory-trimmed for 5% hysteresis; enables precise low-battery warning at defined cell voltage |
| Rising Threshold (VLBIR) | 1.222V - fixed internal reference; defines recovery point to prevent output chatter |
| Supply Current (IQ) | 3.2µA to 6µA - ultra-low quiescent draw extends battery life in always-on monitoring |
| Propagation Delay (tPD) | 9µs - fast response to voltage drops ensures timely system shutdown or alert |
| Output Type | Push-pull active-low - eliminates need for external pull-up; drives logic directly |
| Input Leakage Current | ±5nA - allows use of >1MΩ resistive dividers without accuracy degradation |
Pinout & Package
MAX6775XKB+T is housed in a RoHS-compliant 5-pin SC70 package (2.0mm × 2.1mm footprint), optimized for space-constrained portable devices. Pin 1 = GND, Pin 2 = LBI, Pin 3 = LBO, Pin 4 = N.C., Pin 5 = BATT.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Primary ground reference; required for stable reference and comparator operation |
| 2 | LBI | Low-battery input; connects to resistive divider to sense battery voltage |
| 3 | LBO | Active-low push-pull output; asserts when VLBI falls below 1.1609V |
| 4 | N.C. | No internal connection; must be left unconnected or tied to GND per layout best practice |
| 5 | BATT | Power supply input; powers internal circuitry and sets operating voltage range |
Key Features
| Feature | Design Value |
|---|---|
| 1.0% threshold accuracy over temperature | Ensures reliable low-battery detection across full -40°C to +85°C industrial range without calibration |
| Factory-set 5% hysteresis | Eliminates external components and design effort while preventing false triggers from noise or voltage recovery |
| 3µA typical supply current | Extends operational lifetime in coin-cell or primary-battery applications by minimizing standby drain |
| Push-pull LBO output | Directly interfaces with MCU reset inputs or PMIC enable lines without pull-up resistors or level-shifting |
| Valid output down to VBATT = 1V | Guarantees functional alert generation even during deep discharge, critical for graceful shutdown |

FAQ
What is the exact falling threshold voltage of the MAX6775XKB+T?
The MAX6775XKB+T has a factory-trimmed falling threshold (VLBIF) of 1.1609V at +25°C, specified over the full -40°C to +85°C temperature range. This value corresponds to its 5% hysteresis option and is guaranteed by design, not typical. The rising threshold remains fixed at 1.222V, resulting in a 61.1mV hysteresis voltage that eliminates output chatter during battery recovery.
Does the MAX6775XKB+T require an external pull-up resistor on its LBO pin?
No, the MAX6775XKB+T features a push-pull LBO output, so no external pull-up resistor is required. This simplifies PCB layout and reduces BOM count. The output actively drives low (≤0.3V at 100µA sink) and high (≥0.8×VBATT at 100µA source), enabling direct connection to microcontroller reset inputs or power-management IC enable pins without level-shifting.
Can the MAX6775XKB+T operate reliably at VBATT = 1.2V?
Yes, the MAX6775XKB+T is fully specified to operate from VBATT = 1.2V to 5.5V and guarantees valid LBO logic states down to VBATT = 1V. At 1.2V, it maintains 3.2µA to 6µA supply current and retains 1.0% threshold accuracy over temperature - making it suitable for deep-discharge monitoring in primary alkaline or NiMH systems where voltage sags below 1.5V.
How does the 5% hysteresis in the MAX6775XKB+T improve system reliability?
The 5% hysteresis in the MAX6775XKB+T creates a 61.1mV gap between its 1.1609V falling and 1.222V rising thresholds, preventing output oscillation caused by input noise or battery terminal voltage recovery after load removal. This eliminates false low-battery assertions and ensures clean, single-event triggering - critical for deterministic shutdown sequencing in portable electronics without software debouncing overhead.
What package type and pin count does the MAX6775XKB+T use?
The MAX6775XKB+T uses a 5-pin SC70 package (package code X5-1), measuring 2.0mm × 2.1mm with 0.65mm pitch. Its pinout is: Pin 1 = GND, Pin 2 = LBI, Pin 3 = LBO, Pin 4 = N.C., Pin 5 = BATT. This compact RoHS-compliant footprint supports high-density layouts in smartphones, wearables, and other miniaturized battery-powered systems.
