Product details
Overview
TPS2818MDBVREP from Texas Instruments is an inverting single-channel high-speed MOSFET driver in a 5-pin SOT-23 (DBV) package, delivering up to 2 A peak output current with 25 ns max rise/fall times and 40 ns max propagation delay into 1 nF load. It features an internal voltage regulator (8–40 V input), operates from –55°C to 125°C, and is designed for gate driving in high-frequency DC/DC converters and motor control stages.
For engineers reviewing the TPS2818MDBVREP datasheet, TPS2818MDBVREP pinout, TPS2818MDBVREP application, or TPS2818MDBVREP equivalent, this page provides verified electrical parameters, terminal functions, thermal performance data, and validated alternative options for ruggedized power stage design.
Technical Context
The TPS2818MDBVREP implements a BiCMOS output stage enabling fast switching with low shoot-through current and rail-to-rail drive capability. Its inverting logic architecture (OUT = NOT IN) and absence of active pullup circuit distinguish it from TPS2816/TPS2817 variants.
It integrates a series-connected voltage regulator that accepts 8–40 V on VDD and delivers ~11.5 V at up to 20 mA on VCC, allowing direct powering of PWM controllers or auxiliary circuitry - provided total package dissipation remains within 227 mW at 80°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output configuration | Inverting driver: OUT = NOT IN - enables direct interface with non-inverted PWM signals requiring polarity inversion before gate drive. |
| Peak output current | 2 A - sufficient to rapidly charge/discharge MOSFET gates with >2000 pF input capacitance in high-frequency SMPS. |
| Rise/fall time | 25 ns max (VCC = 14 V, CL = 1 nF) - supports switching frequencies beyond 10 MHz in optimized layouts. |
| Propagation delay | 40 ns max (VCC = 14 V, CL = 1 nF) - ensures tight timing control in synchronous rectification and phase-shifted topologies. |
| Regulator input range | VDD = 8–40 V - allows direct connection to unregulated 24 V or 36 V industrial rails without external LDO. |
| Operating temperature | –55°C to 125°C ambient - qualified per JEDEC extended-temperature standards including HAST, temperature cycling, and autoclave testing. |
| Supply current (VCC) | 25 µA typ (IN = high/low, VCC = 10 V) - enables ultra-low quiescent operation in always-on power management subsystems. |
Pinout & Package
TPS2818MDBVREP is housed in a 5-pin SOT-23 (DBV) package - surface-mount, tape-and-reel (3000 pcs/reel), RoHS-compliant, MSL Level-1, with NIPDAU lead finish and part marking "PMTM".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Regulator supply input | Accepts 8–40 V unregulated input; powers internal regulator - must not be grounded; connect to VCC if unused. |
| GND (Pin 2) | Power and signal reference | Common return for regulator, driver outputs, and logic inputs - requires low-inductance PCB connection to minimize ground bounce. |
| IN (Pin 3) | Inverting logic input | CMOS-compatible input with 2/3 VCC positive-going and 1/3 VCC negative-going thresholds; no internal pullup (unlike TPS2816/TPS2817). |
| OUT (Pin 4) | Driver output | Capable of ±2 A peak sourcing/sinking; rail-to-rail swing (0.18 V low / 9.1 V high @ 100 mA); drives MOSFET gate directly. |
| VCC (Pin 5) | Driver supply / regulator output | Provides regulated ~11.5 V output (10–13 V range) at ≤20 mA; also serves as main driver supply voltage (4–14 V range when regulator bypassed). |
Key Features
| Feature | Design Value |
|---|---|
| Inverting logic with no active pullup | Eliminates need for external pullup resistors only when used with push-pull controllers; requires external pullup for open-collector sources. |
| Integrated 40 V-input series regulator | Enables single-rail operation from industrial 24 V/36 V supplies while delivering stable 11.5 V for gate drive and auxiliary circuitry. |
| BiCMOS output stage | Delivers 2 A peak current with <1 V saturation drop at 100 mA, minimizing conduction loss during MOSFET transition periods. |
| High-temperature qualification | Validated for continuous operation at 125°C ambient per JEDEC JESD22-A108, including biased 85/85 and HAST testing. |
| Latch-up immunity | Designed to withstand transient overvoltage events without destructive latch-up - critical in noisy motor drive and industrial power environments. |
Applications
| Industrial DC/DC Converters | Avionics Power Supplies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2819MDBVREP | Noninverting logic (OUT = IN); identical regulator, timing, and thermal specs. | Used where controller output polarity matches required gate drive polarity - avoids external inverter logic. | Select TPS2819MDBVREP when system-level signal chain requires noninverted gate drive; same PCB layout and thermal management apply. |
| TPS2828MDBVREP | No internal regulator; VDD pin is NC; ICC < 15 µA max; same inverting logic and 2 A drive. | Suitable for systems with pre-regulated 12 V supply - eliminates regulator overhead and improves light-load efficiency. | Choose TPS2828MDBVREP when VCC is already regulated at 4–14 V and ultra-low quiescent current (<15 µA) is mandatory. |
Compared with TPS2819MDBVREP, TPS2818MDBVREP provides polarity inversion without added components; versus TPS2828MDBVREP, it trades higher quiescent current for wide-input-voltage regulation - making it optimal for unregulated industrial or avionics rails.

FAQ
What is the logic function of the TPS2818MDBVREP?
The TPS2818MDBVREP is an inverting driver: its output is the logical complement of the input signal (OUT = NOT IN). This is confirmed by the functional block diagram, terminal description ("OUT = IN" applies only to noninverting variants), and distinction from TPS2816/TPS2817 which include active pullup. The device has no internal pullup resistor on the IN pin.
Can the TPS2818MDBVREP operate without connecting VDD?
No - VDD must be connected to a valid 8–40 V supply if the internal regulator is used. If the regulator is not needed, VDD should be tied to VCC per datasheet guidance; leaving VDD floating or grounding it will damage the regulator. The TPS2818MDBVREP requires VCC (4–14 V) for driver operation regardless of VDD connection.
What is the maximum continuous output current rating for the TPS2818MDBVREP?
The TPS2818MDBVREP is rated for ±100 mA continuous output current (absolute maximum rating), though it delivers up to 2 A peak current for short durations during MOSFET gate charging. Continuous current is limited by package thermal dissipation (227 mW at 80°C ambient), not output stage capability.
Does the TPS2818MDBVREP support 24 V input rails directly?
Yes - the TPS2818MDBVREP's internal regulator accepts VDD input from 8 V to 40 V, making it compatible with standard 24 V industrial rails. At VDD = 24 V, the regulator delivers ~11.5 V on VCC at up to 20 mA, enabling direct powering of gate drivers and PWM ICs without external regulation.
How does the TPS2818MDBVREP differ from the TPS2816MDBVREP?
The TPS2818MDBVREP omits the active pullup circuit present in the TPS2816MDBVREP, resulting in lower input current (0.2 µA vs 650 µA at IN = 0 V) and eliminating external pullup requirements only for push-pull controllers. Both share identical regulator, timing, and thermal specifications, but TPS2816MDBVREP supports open-collector PWM inputs natively.
