Product details
Overview
LTC2913IMS-2#TRPBF from Analog Devices (formerly Linear Technology) is a dual-input, dual-threshold voltage supervisor IC designed for simultaneous undervoltage (UV) and overvoltage (OV) monitoring of two independent power rails. It features adjustable UV/OV trip points with ±1.5% threshold accuracy, 44 μA quiescent current, open-drain UV/OV outputs, and a dedicated DIS pin to disable both outputs. It is used in desktop/notebook computers and network servers for core/I/O supply integrity assurance.
For engineers reviewing the LTC2913IMS-2#TRPBF datasheet, LTC2913IMS-2#TRPBF pinout, LTC2913IMS-2#TRPBF application, or LTC2913IMS-2#TRPBF equivalent, key selection considerations include its dual-rail UV/OV detection capability, guaranteed operation down to VCC = 1 V, glitch-filtered timing, adjustable reset timeout via external capacitor, and DIS-enabled output disable functionality for system-level control sequencing.
Technical Context
The LTC2913IMS-2#TRPBF implements two independent comparator pairs per monitored rail - one for VHn (undervoltage detection) and one for VLn (overvoltage detection) - each referenced to a precise 500 mV internal threshold. Its architecture includes an integrated shunt regulator on VCC (6.6 V typical), enabling direct operation from supplies up to 6 V or regulated operation from higher voltages using an external series resistor.
Unlike the LTC2913-1 variant, the -2 version replaces the LATCH pin with DIS (Pin 8), providing active-high disable control over both UV and OV outputs. The TMR pin supports externally programmable timeout (6–14 ms with 1 nF), and all inputs exhibit ±15 nA leakage and 1.5% threshold accuracy across –40°C to 85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Operating Range | 2.3 V to 6 V; operates as direct supply input; >6 V requires external current-limiting resistor due to internal 6.6 V shunt regulator |
| Threshold Voltage (VUOT) | 500 mV ±1.5%; defines trip point for all VHn/VLn comparators - enables precise UV/OV detection with resistor-divider configuration |
| Quiescent Current (ICC) | 44 μA typical at 2.3–6 V; ensures micropower operation suitable for battery-backed or always-on monitoring circuits |
| UV/OV Output Type | Open-drain with weak internal pull-up to VCC and strong pull-down; supports wired-OR logic and external pull-up flexibility |
| Reset Timeout (tUOTO) | 6–14 ms (typ. 8.5 ms with 1 nF); programmable via CTMR capacitor on TMR pin; holds UV/OV asserted after fault clearance |
| DIS Input Function | Active-high disable (VIH ≥ 1.2 V); forces UV/OV high-impedance when asserted - except during VCC UVLO (1–2.1 V) |
| Input Leakage (IVHL) | ±15 nA max at –40°C to 85°C; minimizes divider current error and enables high-impedance sensing networks |
Pinout & Package
Package: 10-Lead MSOP (3mm × 3mm), RoHS-compliant, exposed pad optional (Pin 11 not present in MSOP; only in DFN). Pin count and layout conform to JEDEC MO-187 variation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| VH1 (Pin 1) | Undervoltage Sense Input 1 | Connected to high-side tap of resistor divider; asserts UV when voltage falls below 500 mV |
| VL1 (Pin 2) | Overvoltage Sense Input 1 | Connected to low-side tap of resistor divider; asserts OV when voltage rises above 500 mV |
| VH2 (Pin 3) | Undervoltage Sense Input 2 | Independent second UV channel; identical threshold and timing behavior as VH1 |
| VL2 (Pin 4) | Overvoltage Sense Input 2 | Independent second OV channel; identical threshold and timing behavior as VL1 |
| GND (Pin 5) | Ground Reference | Analog and digital ground return; must be low-impedance path for accurate threshold referencing |
| OV (Pin 6) | Overvoltage Output | Open-drain logic output; pulled low during OV condition; disabled when DIS = high |
| UV (Pin 7) | Undervoltage Output | Open-drain logic output; pulled low during UV condition; disabled when DIS = high |
| DIS (Pin 8) | Output Disable Control | Active-high input (VIH ≥ 1.2 V); disables UV/OV outputs except during VCC UVLO (1–2.1 V) |
| TMR (Pin 9) | Timeout Timer Control | Connects to external capacitor (≥10 pF) to set reset pulse width; tie to VCC to bypass timeout |
| VCC (Pin 10) | Supply Voltage Input | Power input with internal 6.6 V shunt regulator; bypass with ≥0.1 μF ceramic capacitor to GND |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent UV/OV monitoring channels | Enables concurrent supervision of two critical rails (e.g., 5 V and 3.3 V) with separate resistor-divider configurations |
| Adjustable trip thresholds via resistor dividers | Supports custom UV/OV setpoints (e.g., 4.5 V UV / 5.5 V OV on 5 V rail) using standard 1% resistors and 500 mV reference |
| Glitch-immune comparator filtering | Integrates comparator output before asserting UV/OV, rejecting transients <400 μs at 1% overdrive - eliminates false resets |
| Programmable reset timeout with disable | TMR pin allows precise pulse-width control (ms-range); DIS pin provides system-level override without PCB changes |
| Guaranteed operation down to VCC = 1 V | Ensures reliable UV assertion and OV blocking during brown-out and power-up sequences, even under marginal supply conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail voltage monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2913IMS-1#TRPBF | Replaces DIS with LATCH pin; OV output latches low on fault and clears only when LATCH is pulled high | Suitable for systems requiring persistent fault indication until manual or firmware-initiated clear | Select LTC2913IMS-1#TRPBF when latch-and-hold behavior is required instead of disable-on-demand |
| LTC2904CMS8#TRPBF | Single-supply, 3-state programmable dual monitor; no DIS pin; fixed 2.5 V/3.3 V thresholds or adjustable via external resistors | Lacks dual independent UV/OV per rail; offers adjustable tolerance but no programmable timeout or disable function | Choose LTC2904CMS8#TRPBF only for simpler, cost-sensitive designs where timeout disable is unnecessary and rail count is lower |
Compared with LTC2913IMS-1#TRPBF and LTC2904CMS8#TRPBF, the LTC2913IMS-2#TRPBF uniquely combines active output disable (DIS), dual-rail independent UV/OV detection, and programmable timeout - making it optimal for systems requiring dynamic reset control and high-accuracy multi-rail supervision without latch persistence.

FAQ
What is the function of the DIS pin on the LTC2913IMS-2#TRPBF?
The DIS (Disable) pin on the LTC2913IMS-2#TRPBF is an active-high control input that disables both UV and OV outputs when pulled to ≥1.2 V. When DIS is asserted, UV and OV are forced into high-impedance (open-drain off) state - except during VCC undervoltage lockout (UVLO), where UV remains asserted low. This enables precise system-level reset gating without modifying the monitoring circuit itself. The DIS pin has a 2 μA internal pull-down, so it defaults to enabled when left unconnected.
How does the LTC2913IMS-2#TRPBF achieve ±1.5% threshold accuracy across temperature?
The LTC2913IMS-2#TRPBF achieves ±1.5% threshold accuracy over –40°C to 85°C by using a trimmed, bandgap-referenced 500 mV comparator input threshold with matched internal transistor pairs and curvature-compensated biasing. This specification is guaranteed in production test and applies to all VHn and VLn inputs. External resistor-divider accuracy contributes additional error - e.g., 1% resistors add ~1% to total trip-point uncertainty - but the IC's intrinsic threshold drift remains within ±1.5% across the full operating range.
Can the LTC2913IMS-2#TRPBF monitor negative voltages?
No, the LTC2913IMS-2#TRPBF is designed exclusively for positive-voltage monitoring. Its VHn and VLn inputs operate with respect to GND and require input voltages between –0.3 V and 7.5 V. For negative rail supervision, Analog Devices offers the LTC2909 or LTC2914, which support dedicated negative-input configurations with separate reference paths. Attempting to apply negative voltage to VHn/VL2 of the LTC2913IMS-2#TRPBF violates Absolute Maximum Ratings and may damage the device.
What is the minimum capacitor value required on the TMR pin of the LTC2913IMS-2#TRPBF?
The minimum capacitor value required on the TMR pin of the LTC2913IMS-2#TRPBF is 10 pF. This value ensures proper charging/discharging dynamics for the internal timer circuit. Using less than 10 pF may cause inconsistent timeout behavior or failure to assert UV/OV for the intended duration. A 1 nF capacitor yields a typical timeout of 8.5 ms; larger values scale linearly (e.g., 10 nF ≈ 85 ms). The TMR pin may also be tied directly to VCC to bypass the timeout function entirely.
Does the LTC2913IMS-2#TRPBF support operation from a 12 V supply?
Yes, the LTC2913IMS-2#TRPBF supports operation from a 12 V supply via its internal 6.6 V shunt regulator on the VCC pin. To prevent exceeding the 10 mA maximum terminal current rating, a series current-limiting resistor (RZ) must be placed between the 12 V source and VCC. For example, with VCC = 6.6 V and desired ICC = 50 μA, RZ ≈ (12 V − 6.6 V)/50 μA = 108 kΩ. The datasheet provides the full VCC shunt I-V curve to guide RZ selection under worst-case temperature and load conditions.
