Product details
Overview
LTC7000MPMSE#TRPBF from Analog Devices is a high-voltage, fast-turn-on high-side N-channel MOSFET gate driver IC designed for static and switching high-side switch applications up to 135V input. It integrates an internal charge pump for 100% duty cycle operation, delivers 2.2Ω pull-up / 1Ω pull-down gate drive strength, features adjustable overcurrent protection via ISET pin, and supports –55°C to 150°C operating junction temperature. It is used in industrial power distribution systems requiring robust fault management and fast transient response.
For engineers reviewing the LTC7000MPMSE#TRPBF datasheet, LTC7000MPMSE#TRPBF pinout, LTC7000MPMSE#TRPBF application, or LTC7000MPMSE#TRPBF equivalent, key selection criteria include its 135V VIN capability, 35ns propagation delay, integrated current monitor (IMON), adjustable current trip threshold, and MSOP-16 thermally enhanced package with exposed GND pad.
Technical Context
The LTC7000MPMSE#TRPBF implements a level-shifted high-side driver architecture with internal charge pump regulation to maintain BST–TS at ~12V across 3.5V–135V VIN range. Its gate driver outputs (TGUP/TGDN) deliver rail-to-rail swing referenced to TS, enabling full enhancement of external N-MOSFETs even at 100% duty cycle.
Overcurrent protection uses a precision current-sense comparator monitoring ΔVSNS across an external sense resistor, with trip threshold ΔVTH programmable from 20mV to 75mV via ISET pin. Fault timing, automatic retry, and open-drain FAULT flag are controlled by external TIMER capacitor CT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Operating Range | 3.5V to 135V - enables direct connection to wide-input industrial or automotive battery rails without pre-regulation. |
| Propagation Delay | 35ns - ensures precise timing control in high-frequency switching or fast turn-on/turn-off static switch applications. |
| TGUP/TGDN Drive Strength | 2.2Ω pull-up / 1Ω pull-down - minimizes MOSFET switching losses and supports large gate capacitances up to 1nF. |
| Current Sense Threshold | 20mV to 75mV (adjustable via ISET) - allows optimization of sense resistor value for conduction loss vs. noise immunity trade-offs. |
| Operating Junction Temp | –55°C to 150°C - qualified for extended-temperature industrial, aerospace, and downhole applications. |
| Charge Pump Output | Regulated BST–TS ≈ 12V - sustains gate drive voltage for indefinite 100% duty cycle operation without external bootstrap diode/capacitor complexity. |
| IMON Output (LTC7000 only) | 0–1.5V, 20× gain - provides ground-referenced analog current monitoring for system diagnostics or closed-loop control. |
Pinout & Package
Package: 16-lead plastic MSOP (MSE16) with exposed thermal pad (Pin 17 = GND). Thermally enhanced layout requires soldering exposed pad to PCB for θJC = 10°C/W performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RUN (1) | Enable/UVLO control input | Enables device when >1.21V; shuts down to ~1µA when <0.7V; supports precise input undervoltage lockout via resistive divider. |
| VIN (2) | Main high-voltage supply input | Accepts 3.5V–135V; powers internal LDO (VCC) and charge pump; requires ≥0.1µF bypass to GND. |
| VCC (3) | Internal LDO output & driver supply | 10V regulated output (or follows VIN if <10V); powers logic and gate drivers; can be overdriven externally for high-frequency use. |
| VCCUV (4) | VCC undervoltage lockout reference | Sets VCC UVLO threshold (3.5V–7.0V) via resistor divider; prevents unreliable gate drive during low-VCC conditions. |
| FAULT (5) | Open-drain fault indicator | Pulls low during overcurrent or OVLO events; typical 200Ω pull-down; remains asserted until cooldown and reset. |
| TIMER (6) | Fault timing capacitor node | External CT sets warning delay, fault turn-off time, and auto-retry period; connect >3.5V for immediate fault shutdown. |
| INP (7) | CMOS-compatible enable input | Controls TGUP/TGDN state; internal 1MΩ pull-down ensures safe default (TGDN = TS) at startup. |
| OVLO (8) | Input overvoltage lockout input | Triggers fault and disables output when VIN exceeds programmed threshold; tie to GND if unused. |
| ISET (9) | Current trip threshold programming | Sets ΔVTH = VISET/20 (20–75mV); short to GND for min trip (20mV); open for nominal 30mV. |
| IMON (10) | Analog current monitor output | Ground-referenced 0–1.5V output = 20×(VSNS+ – VSNS–); enables real-time load current feedback. |
| TGDN (11) | High-current gate pull-down | Directly pulls MOSFET gate to TS (high-side source); low 1Ω impedance ensures fast turn-off. |
| TGUP (12) | High-current gate pull-up | Pulls gate to BST (bootstrap rail); 2.2Ω impedance supports fast turn-on; optional series resistor controls dV/dt. |
| TS (13) | High-side source reference | Connects to MOSFET source; serves as local ground reference for high-side sensing and driving. |
| BST (14) | Bootstrap supply node | Charged by internal pump to ~12V above TS; requires ≥0.1µF capacitor to TS for stable gate drive. |
| SNS– (15) | Current sense negative input | Kelvin-connected to low side of sense resistor; includes 100Ω series resistor for noise immunity. |
| SNS+ (16) | Current sense positive input | Kelvin-connected to high side of sense resistor; forms differential pair with SNS– for accurate ΔVSNS measurement. |
| GND (17) | Exposed thermal pad | Must be soldered to PCB plane; serves as primary thermal path and electrical ground return. |
Key Features
| Feature | Design Value |
|---|---|
| 100% duty cycle support | Integrated charge pump maintains BST–TS at ~12V regardless of VIN, eliminating need for external bootstrap diode and enabling continuous conduction mode. |
| Adjustable overcurrent protection | ISET pin allows precise setting of current trip threshold (20–75mV), enabling optimization of sense resistor RSENSE for minimal power loss and noise margin. |
| Ground-referenced current monitor | IMON pin delivers 0–1.5V output proportional to load current (20× gain), simplifying system-level current telemetry without isolated amplifiers. |
| Fast, robust gate drive | 35ns propagation delay + 13ns rise/fall times into 1nF load ensure tight timing control; 1Ω/2.2Ω drivers minimize switching losses in high-current MOSFETs. |
| Extended temperature qualification | –55°C to 150°C operating junction range meets requirements for harsh-environment industrial, defense, and energy applications. |

FAQ
What is the maximum input voltage rating for the LTC7000MPMSE#TRPBF?
The LTC7000MPMSE#TRPBF has an absolute maximum VIN rating of 150V and a specified operating range of 3.5V to 135V. This allows direct interface with 48V, 72V, and 110V industrial DC buses, as well as automotive 48V mild-hybrid systems, without external pre-regulation. Operation beyond 135V violates functional specifications and risks permanent damage.
Does the LTC7000MPMSE#TRPBF support 100% duty cycle operation?
Yes, the LTC7000MPMSE#TRPBF supports true 100% duty cycle operation via its integrated charge pump, which regulates BST–TS to ~12V independent of VIN. This eliminates reliance on external bootstrap diodes and capacitors, enabling continuous conduction mode in applications like electronic fuses, battery disconnect switches, and synchronous rectifiers where sustained gate drive is essential.
How does overcurrent protection work on the LTC7000MPMSE#TRPBF?
The LTC7000MPMSE#TRPBF monitors voltage across an external sense resistor (ΔVSNS) using differential inputs SNS+ and SNS–. When ΔVSNS exceeds the programmable threshold ΔVTH (set via ISET pin to 20–75mV), the internal comparator triggers after a delay set by the TIMER capacitor. TGDN is then pulled low to turn off the external MOSFET, and FAULT asserts. An automatic retry occurs after cooldown.
What is the purpose of the IMON pin on the LTC7000MPMSE#TRPBF?
The IMON pin on the LTC7000MPMSE#TRPBF provides a ground-referenced analog voltage output equal to 20×(VSNS+ – VSNS–), ranging from 0V to 1.5V. This enables real-time, isolated-free current monitoring for system diagnostics, closed-loop control, or logging - a feature absent in the LTC7000-1 variant and most competing high-side drivers.
Is the LTC7000MPMSE#TRPBF pin-compatible with other variants in the LTC7000 family?
The LTC7000MPMSE#TRPBF shares identical pinout and package (16-lead MSOP) with all LTC7000 and LTC7000-1 variants, including LTC7000EMSE#TRPBF and LTC7000JMSE-1#TRPBF. However, functional differences exist: LTC7000MP includes RUN, OVLO, ISET, and IMON pins; LTC7000-1 variants omit RUN/OVLO/ISET/IMON. Pin compatibility does not imply functional interchangeability without circuit review.
