Infineon Technologies BTS7710GNUMA1

Overview

BTS7710GNUMA1 from Infineon Technologies is a quad-channel D-MOS high- and low-side power switch IC for DC motor control, integrating one double high-side (SH1/SH2) and two independent low-side (DL1/DL2) switches in a single P-DSO-28-14 package. It delivers 70 mΩ typical R_DS(on) on high-side and 40 mΩ on low-side at 25°C, supports 15 A peak current, operates up to 40 V supply, and features open-drain status flag (ST), under-voltage lockout, and overtemperature shutdown with hysteresis.

For engineers reviewing the BTS7710GNUMA1 datasheet, BTS7710GNUMA1 pinout, BTS7710GNUMA1 application, or BTS7710GNUMA1 equivalent, key selection criteria include configurable H-bridge vs. quad-switch topology, isolated source pins for external current sensing, integrated clamp diodes for inductive load commutation, and differential diagnosis capability via ST output for high-side faults only.

Technical Context

The device implements three vertically stacked DMOS dies-two S-FET logic-level low-side switches and one SMART SIPMOS® double high-side switch-with physically separated leadframes (HS, LS1, LS2) enabling independent thermal management and flexible PCB layout. Each switch pair shares no internal connection between sources or drains beyond package-level metal bridges.

Control logic uses TTL/CMOS-compatible Schmitt-trigger inputs (IH1/IH2) with ESD protection, while analog gate inputs (IL1/IL2) directly drive low-side MOSFET gates. Diagnosis is limited to high-side faults: overtemperature (per switch), undervoltage, and short-circuit-reported via open-drain ST pin requiring external pull-up; no open-load detection is provided.

Key Specifications

Pinout & Package

P-DSO-28-14: 28-pin plastic dual small outline package with exposed thermal pad (leadframe-connected), 1.27 mm pitch, body size 17.9 × 7.5 mm, designed for surface-mount reflow assembly and moderate-power thermal dissipation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad high-/low-side switch applications.

Compared with BTS7710GP, BTS7710GNUMA1 trades thermal headroom for compactness and cost; versus BUZ103SL, it delivers integrated protection and diagnosis at the expense of design flexibility-making it optimal for space-constrained, safety-aware motor control where rapid time-to-market matters.

FAQ

What is the maximum continuous current per channel for BTS7710GNUMA1?

The device supports 8 A continuous drain current per low-side switch (DL1/DL2) and 8 A per high-side switch (SH1/SH2) at T_A = 25°C with proper PCB cooling (6 cm² copper). Derating is required above 25°C ambient; at 85°C, continuous rating drops to ~4.5 A due to R_thJA = 60 K/W and T_J(max) = 150°C limit.

Can BTS7710GNUMA1 drive inductive loads without external freewheeling diodes?

Yes-integrated clamp diodes across each high-side switch (DHVS to SH1/SH2) provide freewheeling paths for inductive kickback during turn-off. However, low-side switches lack internal clamps; external diodes are required across DL1/DL2 if used in single-switch mode with inductive loads.

How does the status flag (ST) indicate specific high-side faults?

ST is an open-drain output that pulls low only during high-side faults: overtemperature (per switch), undervoltage lockout (V_S < V_UVOFF), or short-circuit. It does not report low-side faults or open-load conditions. The truth table on page 7 of the datasheet shows ST = low for all fault states; no encoding distinguishes fault type.

Is the P-DSO-28-14 package lead-free and RoHS compliant?

Yes-BTS7710GNUMA1 is manufactured in a lead-free, halogen-free P-DSO-28-14 package compliant with EU RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 3 (MSL3), requiring bake prior to reflow if exposed to ambient >30°C/60% RH for >168 hours.
