Product details
Overview
TPS48110AQDGXRQ1 from Texas Instruments is an AEC-Q100 Grade 1 (–40°C to +125°C) automotive smart high-side driver IC designed for 12V/24V/48V power distribution systems. It delivers 3.7A peak source and 4A peak sink gate drive, supports 3.5V–80V input range (100V abs max), features ±2% accurate analog current monitoring (IMON), and provides fast 4µs short-circuit protection - enabling robust control of external back-to-back N-channel MOSFETs in body control modules and battery management systems.
For engineers reviewing the TPS48110AQDGXRQ1 datasheet, TPS48110AQDGXRQ1 pinout, TPS48110AQDGXRQ1 application, or TPS48110AQDGXRQ1 equivalent, key selection considerations include its integrated two-level overcurrent protection with adjustable thresholds (IWRN/ISCP), remote diode-based overtemperature sensing (DIODE/FLT_T), precise ±2% UVLO/OV (<±2%), and 1.6µA shutdown current - all critical for functional safety-compliant automotive power switching designs.
Technical Context
The TPS48110AQDGXRQ1 implements a high-voltage smart gate driver architecture with integrated charge pump (12V, 100µA), dual-stage overcurrent detection (warning + circuit breaker), and open-drain fault signaling (FLT_I for overcurrent, FLT_T for overtemperature). Its gate driver outputs (PU/PD) are optimized for driving parallel N-FETs with strong pull-up/pull-down capability and configurable slew rate via external R-C networks on INP.
Unlike the TPS48111Q1 variant, this part omits the pre-charge driver (G/INP_G) and includes overvoltage protection (OV pin) with ±2% accuracy and 4µs short-circuit response - making it suitable for applications requiring load voltage clamping but not capacitive pre-charging, such as HVAC heater drivers and DC/DC converter primary-side switches.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.5V to 80V operating; 100V absolute maximum - supports 12V/24V/48V automotive systems with transient tolerance. |
| Gate Drive Strength | 3.7A peak source (PU), 4A peak sink (PD) - enables fast switching of parallel high-current N-channel MOSFETs. |
| Current Sense Accuracy | ±2% at 30mV sense voltage (VSNS) on IMON output - enables precise energy management and diagnostic current reporting. |
| Short-Circuit Response | 4µs propagation delay (VCS+–VCS– → PD↓) - provides rapid fault isolation before destructive energy dissipation. |
| Shutdown Current | 1.6µA typical at 48V (EN/UVLO = Low) - minimizes standby power loss in always-on vehicle subsystems. |
| Overvoltage Protection | Adjustable threshold with <±2% accuracy (OV pin) - allows precise clamping of VOUT during load dump or regenerative events. |
| Operating Temp Range | –40°C to +125°C ambient (AEC-Q100 Grade 1) - qualified for under-hood and power distribution box environments. |
Pinout & Package
DGX package: 19-pin VSSOP (5.10mm × 3.00mm) with pin-removed isolation between high- and low-voltage sections (0.8mm clearance).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN/UVLO | Enable / Undervoltage Lockout Input | CMOS-compatible control pin; >1.18V enables operation; <0.3V forces 1.6µA shutdown; internal 60nA pull-down keeps device off when floating. |
| OV | Overvoltage Threshold Input | Resistive divider sets cut-off voltage; asserts PD↓ when exceeded; must be tied to GND if unused. |
| INP | Gate Control Input | CMOS input referenced to GND; controls PU/PD state; internal pull-down ensures safe default OFF. |
| FLT_I | Open-Drain Overcurrent Fault Flag | Asserts low when TMR reaches 1.1V; indicates imminent FET turn-off due to overcurrent; remains asserted until fault clears and auto-retry expires. |
| FLT_T | Open-Drain Overtemperature Fault Flag | Asserts low upon remote diode-sensed junction temperature >150°C; supports auto-retry with fixed 512ms timer. |
| IMON | Analog Current Monitor Output | Sources scaled current proportional to RSNS voltage; ±2% accuracy at 30mV VSNS; connect RIMON to GND to convert to voltage. |
| IWRN | Warning-Level Overcurrent Threshold | Resistor to GND sets first-stage OCP threshold (e.g., 30.6mV with 39.7kΩ); tie to GND to disable warning level. |
| TMR | Fault Timer Input | Capacitor to GND sets timing for FLT_I assertion, fault turn-off, and auto-retry intervals; open = fastest response. |
| DIODE | Remote Temperature Sensing Input | Connects to base-collector of MMBT3904 BJT; enables remote junction temperature monitoring; tie to GND if unused. |
| PU / PD | High-Side Gate Driver Outputs | PU pulls up to BST (12V), PD pulls down to SRC; direct connection to FET gate enables fastest switching; resistor limits dV/dt. |
| BST / SRC | Bootstrap Supply Terminals | BST supplies high-side gate drive; SRC is source reference for external FET; CBST ≥ Qg(tot) of FET required. |
| CS+ / CS− | Current Sense Differential Inputs | Measure voltage across external RSNS; 50–100Ω resistor from CS+ to RSNS improves noise immunity. |
| GND | System Ground Reference | Primary ground return for internal regulators, logic, and fault flags; must be low-impedance connection to system GND. |
| N.C. | No Connect | Pin 11 is unconnected; no PCB trace or component should attach to this terminal. |
Key Features
| Feature | Design Value |
|---|---|
| Functional Safety Documentation Support | TI provides FIT rate data, failure mode analysis, and safety manual to accelerate ISO 26262 ASIL-B system certification. |

FAQ
What is the absolute maximum input voltage rating for the TPS48110AQDGXRQ1?
The TPS48110AQDGXRQ1 has an absolute maximum input voltage rating of 100V on the VS, CS+, and CS– pins relative to GND. This rating allows robust operation during automotive load-dump transients while maintaining reliable gate drive performance up to 80V continuous input. Exceeding 100V may cause permanent damage per TI's Absolute Maximum Ratings table.
Does the TPS48110AQDGXRQ1 support overvoltage protection, and how is it configured?
Yes, the TPS48110AQDGXRQ1 supports adjustable overvoltage protection via the OV pin. A resistor divider from VS to GND sets the trip threshold, with ±2% accuracy across temperature. When the OV pin voltage exceeds 1.18V (rising), the PD output is pulled low to turn off the external FET. The OV pin must be tied to GND if unused - leaving it floating defaults to enabling the FET.
How does the TPS48110AQDGXRQ1 implement short-circuit protection, and what is its response time?
The TPS48110AQDGXRQ1 uses differential current sensing (CS+/CS–) to detect short circuits and triggers PD turn-off with a 4µs propagation delay from sense voltage crossing the SCP threshold (e.g., 40mV). This fast response is confirmed in TI's Electrical Characteristics table and Figure 6-12, ensuring protection before destructive energy builds in high-current automotive loads.
Can the TPS48110AQDGXRQ1 monitor load current accurately, and what is the specified accuracy?
Yes, the TPS48110AQDGXRQ1 provides an analog current monitor output (IMON) with ±2% accuracy at 30mV sense voltage (VSNS), as specified in Section 6.5 of the datasheet. This accuracy holds across –40°C to +125°C and enables precise diagnostics and energy management without external amplifiers - verified by TI's test conditions and Figure 6-9.
What thermal protection mechanism does the TPS48110AQDGXRQ1 use, and how is it implemented?
The TPS48110AQDGXRQ1 implements remote overtemperature protection using the DIODE pin, which sources 160µA to bias an external MMBT3904 BJT. Junction temperature is inferred from the BJT's VBE, and FLT_T asserts low when sensed temperature exceeds 150°C (rising threshold). This method avoids on-die thermal drift and supports placement near hot spots like power FETs.
