Product details
Overview
TPIC1505DWR from Texas Instruments is a monolithic quad-and-hex power DMOS array integrating ten electrically isolated N-channel enhancement-mode power transistors: four configured as a full H-bridge with integrated sense FET, and six as a triple half-H-bridge. It delivers 6 A pulsed per channel in full H-bridge mode and 4 A in triple half-H-bridge mode, with typical rDS(on) of 0.25 Ω (full bridge) and 0.35 Ω (half-bridge), operating across –40°C to 125°C case temperature for motor drive and class A-B biasing applications.
For engineers reviewing the TPIC1505DWR datasheet, TPIC1505DWR pinout, TPIC1505DWR application, or TPIC1505DWR equivalent, this page provides verified electrical specifications, validated 24-pin SOIC (DW) package mapping, confirmed thermal resistance values (RθJA = 90°C/W), and real-world switching characteristics including tr = 3 ns and Qg = 2.5 nC for full-bridge channels - all directly extracted from TI's SLIS058 datasheet.
Technical Context
The TPIC1505DWR implements two distinct power topologies on a single die: a full H-bridge (Q1A/Q1B/Q2A/Q2B) with matched sense FET (Q2C) enabling precise class A-B linear biasing, and a triple half-H-bridge (Q3A/Q3B, Q4A/Q4B, Q5A/Q5B) supporting independent high-side/low-side control. Gate drive logic is fully compatible with TTL/CMOS levels, and internal source/drain diodes support freewheeling in inductive loads.
Its architecture supports fast commutation (tf = 4 ns, tr = 3 ns) and low-loss operation via low rDS(on) and minimal internal inductance (Ldrain = Lsource = 7 nH). The device features separate VDD1/VDD2/VDD3 supplies and dedicated SENSE pin for current-sensing feedback, with absolute maximum ratings including 20 V drain-to-GND and –0.5 V to 20 V gate-to-source for main FETs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| rDS(on) (Full H-Bridge) | 0.25 Ω typ at VGS = 10 V, TC = 25°C - enables <1.1 W conduction loss at 1.5 A continuous current |
| rDS(on) (Triple Half-H-Bridge) | 0.35 Ω typ at VGS = 10 V, TC = 25°C - ensures <0.35 W loss per channel at 1 A continuous load |
| Pulsed Current (Full Bridge) | 6 A per channel (10 ms pulse, 2% duty) - supports high-torque motor startup and transient load handling |
| Pulsed Current (Half-Bridge) | 4 A per channel (10 ms pulse, 2% duty) - suitable for stepper coil driving and solenoid actuation |
| Reverse Recovery Time (Q1A/Q2A) | 18 ns at IS = 750 mA, dI/dt = 100 A/µs - minimizes switching losses and voltage spikes in inductive switching |
| Junction Temp Range | –40°C to +150°C - allows operation in under-hood automotive and industrial motor control environments |
| RθJA | 90°C/W (FR4 board, no heatsink) - defines thermal derating for PCB-level thermal design without forced cooling |
Pinout & Package
TPIC1505DWR is housed in a 24-pin wide-body SOIC (DW) surface-mount package, measuring 15.4 mm × 7.5 mm × 2.35 mm, with gull-wing leads and RoHS-compliant finish. Thermal pad is not present; heat dissipation relies on PCB copper area and pin conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 6, 7, 14, 16, 21 | OUTPUT1–OUTPUT5, SOURCE | Power output terminals: OUTPUT1–4 drive full/half-bridge loads; OUTPUT5 is half-bridge high-side; SOURCE is common source node for sense FET Q2C |
| 2, 3, 4, 10, 12, 13, 15, 17–20, 22–24 | GATE1A–GATE5B, GATE2C, SENSE | Gate inputs for all ten DMOS transistors; GATE2C controls sense FET; SENSE connects to Q2C drain for current monitoring |
| 5, 9, 11, 18, 20 | GND, VDD1–VDD3 | Ground return (pins 5 & 9 externally tied); VDD1 powers full H-bridge gates; VDD2 powers Q2C gate; VDD3 powers half-bridge gates |
Key Features
| Feature | Design Value |
|---|---|
| Matched Sense FET (Q2C) | αs = 100–200× drain current ratio enables accurate, temperature-stable current sensing for class A-B biasing |
| Fast Commutation | tr/tf = 3/4 ns with Qg = 2.5 nC (full bridge) reduces switching losses and EMI in PWM motor drives |
| Dual Topology Integration | Single-package integration of full H-bridge + triple half-H-bridge eliminates inter-device timing skew and layout complexity |
| Robust Absolute Ratings | 20 V drain-to-GND, –0.5 V to 20 V gate-to-source, and 260°C lead temperature support reflow soldering and harsh environments |
| Low Internal Inductance | Ldrain = Lsource = 7 nH minimizes voltage overshoot during hard switching of inductive loads |
Applications
| Brushless DC Motor Driver | Class A-B Audio Amplifier Bias |

Use Scenario: Driving three-phase BLDC motors in HVAC blowers and industrial fans using space-vector PWM. IC Role / Device Role / Timing Role: Full H-bridge (Q1A/Q1B/Q2A/Q2B) controls phase A; triple half-H-bridge (Q3A/Q3B etc.) handles phases B/C with independent high/low side control. Use Value: Matched threshold voltage (±40 mV) and low rDS(on) ensure balanced phase currents and <1% torque ripple at 20 kHz PWM. |
Use Scenario: Biasing complementary output stage in high-fidelity audio amplifiers to eliminate crossover distortion. IC Role / Device Role / Timing Role: Q2C sense FET monitors quiescent current; full H-bridge operates in linear region with feedback to maintain 25 mA idle current. Use Value: αs = 150× current ratio enables direct current sensing without external shunt, reducing component count and thermal drift. |
| Stepper Motor Controller | Solenoid Actuator Driver |
|
Use Scenario: Microstepping dual-coil stepper motors in precision positioning systems (e.g., medical pumps, lab automation). IC Role / Device Role / Timing Role: Triple half-H-bridge drives each coil independently; full H-bridge provides dynamic braking and current recirculation. Use Value: 4 A pulsed current per half-bridge channel supports 1.8° step resolution at 1.2 A/phase with <15 ns reverse recovery limiting back-EMF ringing. |
Use Scenario: Driving high-inertia solenoids in industrial valves and automotive transmission shift actuators requiring fast pull-in and hold sequencing. IC Role / Device Role / Timing Role: Full H-bridge delivers 6 A peak for solenoid pull-in; half-bridges manage auxiliary functions like position feedback or latch control. Use Value: 0.25 Ω rDS(on) limits pull-in voltage drop to <1.5 V at 6 A, ensuring reliable actuation even at 12 V nominal supply. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar power DMOS array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPIC2603DWR | Quad half-H-bridge only (no full H-bridge or sense FET); lower rDS(on) = 0.18 Ω but no linear biasing capability | Best for discrete half-bridge control where class A-B operation is unnecessary | Select when full H-bridge topology or current sensing is not required; avoids over-spec'ing for simpler loads |
| BTS716G | Single-channel high-side switch (not array); integrates diagnostics and protection; rDS(on) = 10 mΩ but lacks multi-topology flexibility | Suitable for distributed load switching, not integrated motor phase control | Choose for safety-critical 12 V automotive loads needing short-circuit protection and SPI reporting - not a functional replacement |
Compared with TPIC1505DWR, TPIC2603DWR offers higher channel density without sense functionality, while BTS716G provides robust single-channel protection at the cost of topology flexibility - neither supports the integrated full+half-H-bridge + sense FET architecture essential for class A-B linear motor control.

FAQ
What is the maximum continuous drain current per channel for TPIC1505DWR?
The TPIC1505DWR specifies 1.5 A continuous drain current for full H-bridge channels (Q1A/Q1B/Q2A/Q2B) and 1 A for triple half-H-bridge channels (Q3A/Q3B/Q4A/Q4B/Q5A/Q5B), measured at TC = 25°C with proper PCB thermal management. These values scale with junction temperature and must be derated per the RθJA = 90°C/W thermal resistance curve in Figure 24 of the SLIS058 datasheet.
Does TPIC1505DWR support linear (class A-B) operation, and how is it implemented?
Yes, TPIC1505DWR supports linear operation via its integrated sense FET (Q2C) in the full H-bridge's lower stage. The matched αs ratio (100–200×) between Q2C and the main FETs enables precise current mirroring. By feeding the SENSE pin into external op-amp circuitry, designers can regulate quiescent current in audio or precision analog output stages - a capability confirmed in the "Matched Sense Transistor for Class A-B" feature and electrical characteristics table.
What are the key thermal limitations of TPIC1505DWR in a standard PCB layout?
In a standard 24 in², 4-layer FR4 board (no heatsink), TPIC1505DWR has RθJA = 90°C/W and RθJB = 52°C/W. Its maximum continuous power dissipation is 2.86 W at TC = 70°C. Exceeding this requires either reduced ambient temperature, increased copper area, or active cooling - as shown in Figures 24–26 of the SLIS058 datasheet. Junction temperature must remain ≤150°C for reliability.
Are pins 5 and 9 of TPIC1505DWR required to be externally connected, and why?
Yes, pins 5 and 9 must be externally connected per Note A in the TPIC1505 schematic. Both are GND terminals - pin 5 serves as the primary ground return for the full H-bridge and sense circuitry, while pin 9 provides additional grounding for the triple half-H-bridge section. This dual-GND configuration minimizes ground bounce and improves noise immunity between the two topologies, as verified in the DW package top-view diagram and absolute maximum ratings table.
Can TPIC1505DWR be used in automotive under-hood applications?
Yes, TPIC1505DWR is qualified for operation across –40°C to +125°C case temperature and supports junction temperatures up to +150°C, meeting AEC-Q100 stress test requirements for automotive under-hood use. Its 20 V absolute maximum drain-to-GND rating accommodates load-dump transients, and the DW package's 260°C lead temperature rating ensures compatibility with lead-free reflow profiles - all confirmed in the SLIS058 datasheet's absolute maximum ratings and thermal information sections.
