Product details
Overview
LTC2910IDHC#TRPBF from Analog Devices (formerly Linear Technology) is an octal-input voltage supervisor IC designed for simultaneous monitoring of up to eight positive or negative supply rails in power management systems. It features ±1.5% threshold accuracy over –40°C to +85°C, 50μA quiescent current, adjustable reset timeout (6–14ms), and dual open-drain RST/RST outputs. It is used in multi-rail server power supplies to ensure safe boot and fault recovery.
For engineers reviewing the LTC2910IDHC#TRPBF datasheet, LTC2910IDHC#TRPBF pinout, LTC2910IDHC#TRPBF application, or LTC2910IDHC#TRPBF equivalent, key selection criteria include input polarity configurability via SEL pin, buffered 1V reference output, glitch-immune comparator architecture, VCC shunt regulation up to 6.9V, and guaranteed operation down to VCC = 1V.
Technical Context
The LTC2910IDHC#TRPBF integrates eight independent comparators each referenced to a precision 0.5V internal threshold, with input polarity selectable per pair via a three-state SEL pin. Its glitch filtering uses integrated low-pass stages before reset logic to suppress transients without adding hysteresis-induced trip-point error.
It implements a programmable reset timeout using an external capacitor on TMR (6–14ms typical), supports UVLO at VCC = 2.0V (±0.1V), and provides a buffered 1V reference (±15mV over temperature) capable of sourcing/sinking ±1mA. The device operates from VCC = 2.3V to 6V or higher via internal 6.6V shunt regulator.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Count | 8 independent voltage monitor inputs (V1–V8), configurable for positive or negative rail monitoring |
| Threshold Accuracy | ±1.5% over full –40°C to +85°C range - ensures reliable reset assertion across industrial temperature environments |
| Quiescent Current | 50μA typical - enables use in always-on, low-power system supervision without significant battery drain |
| Reset Timeout Range | 6ms to 14ms (adjustable via CTMR capacitor) - guarantees minimum reset pulse width for stable power-up sequencing |
| VCC Operating Range | 2.3V to 6V direct supply; >6V supported via internal 6.6V shunt regulator with external current-limiting resistor |
| Reference Output | 1.000V ±15mV buffered REF pin - provides stable offset for negative-supply divider networks |
| Output Type | Dual open-drain RST (active-low) and RST (active-high) - supports wired-OR fault aggregation and flexible logic-level interfacing |
Pinout & Package
Package: 16-lead (5mm × 3mm) plastic DFN (DHC16), exposed pad (Pin 17) optional GND connection. Thermal resistance θJA = 43.5°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V1–V6 (Pins 1–6) | Positive-voltage monitor inputs | Assert reset when voltage falls below 0.5V; tied to VCC if unused |
| V7, V8 (Pins 7–8) | Polarity-configurable inputs | Reset triggered when voltage <0.5V (positive mode) or >0.5V (negative mode), per SEL state |
| VCC (Pin 16) | Supply input / shunt regulator | Accepts 2.3–6V directly; regulates >6V supplies internally with ≤10mA max current |
| RST (Pin 11) | Open-drain active-low reset | Pulled low during fault or UVLO; weak internal pull-up to VCC; sinks ≥2.5mA at VOL ≤0.3V |
| RST (Pin 12) | Open-drain active-high reset | Pulled high during fault or UVLO; weak internal pull-up to VCC; drives logic-high reset signal |
| REF (Pin 10) | Buffered 1V reference output | Sources/sinks ±1mA; drives ≤1nF capacitive load; used as offset for negative-rail sensing dividers |
| SEL (Pin 14) | Three-state polarity select | GND/VCC/open configures V7/V8 polarity combinations per Table 1 - no external components required |
| TMR (Pin 15) | Reset timeout timing capacitor node | CTMR ≥10pF sets delay (e.g., 1nF → 8.5ms); tie to VCC to bypass timer |
| DIS (Pin 13) | Reset output disable | Pull high to inhibit RST/RST assertion except during VCC UVLO; internal 2μA pull-down |
| GND (Pin 9) | Device ground reference | Primary return path for all analog and digital circuitry; connects to exposed pad (optional) |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2914HGN#PBF | Quad-input (not octal); supports UV/OV on all inputs; includes watchdog timer; SSOP-16 only | Used where overvoltage detection and watchdog functionality are required alongside UV monitoring | Select when dual-threshold (UV+OV) per rail and system-level watchdog capability are mandatory |
| LTC2908CMS8E#TRPBF | Six-input (four fixed, two adjustable); SOT-23-8 package; no negative rail support; no REF output | Targeted at space-constrained, single-rail or dual-rail applications with simpler topology | Choose for cost-sensitive, low-pin-count designs where only 1.2V/1.8V/3.3V/5V monitoring is needed |

FAQ
What is the operating temperature range for the LTC2910IDHC#TRPBF?
The LTC2910IDHC#TRPBF is rated for –40°C to +85°C ambient operation (Industrial grade). This is confirmed by the "I" suffix in the part number and verified in the Absolute Maximum Ratings table, where all key parameters including VRT, tRST, and ICC are specified over this full range with ● marking.
Can the LTC2910IDHC#TRPBF monitor negative voltages, and how is polarity configured?
Yes, the LTC2910IDHC#TRPBF can monitor negative voltages on V7 and V8 inputs using its buffered 1V REF output to form a level-shifted divider. Polarity is set by the three-state SEL pin: tied to GND configures both V7 and V8 for negative monitoring (reset when voltage >0.5V); tied to VCC configures both for positive monitoring (reset when <0.5V); left open configures V7 positive / V8 negative.
What is the function of the DIS pin on the LTC2910IDHC#TRPBF?
The DIS (Disable) pin on the LTC2910IDHC#TRPBF disables RST and RST outputs during normal operation when pulled high, preventing reset assertion regardless of input faults. However, during VCC undervoltage lockout (UVLO <2.0V), RST asserts low and RST asserts high regardless of DIS state - ensuring fail-safe response to supply collapse.
How is the reset timeout period adjusted on the LTC2910IDHC#TRPBF?
The reset timeout period on the LTC2910IDHC#TRPBF is set by an external capacitor (CTMR) connected between Pin 15 (TMR) and GND. The relationship is tRST ≈ 9ms/nF (e.g., 1nF yields ~8.5ms). Tying TMR to VCC disables the timeout, causing immediate RST/RST deassertion once all inputs recover. Minimum CTMR is 10pF.
Does the LTC2910IDHC#TRPBF require external components for basic operation?
No - the LTC2910IDHC#TRPBF requires only a 0.1μF bypass capacitor on VCC for stable operation. All eight input thresholds are fixed at 0.5V; polarity configuration uses the SEL pin without resistors; REF is internally buffered; and RST/RST have internal weak pull-ups. External resistors are needed only for scaling input voltages above 0.5V (e.g., 5V, 12V rails).
