Product details

Overview

BTS707NTMA1 from Infineon Technologies is a dual-channel Smart High-Side Power Switch based on vertical N-channel SIPMOS technology, featuring integrated charge pump, CMOS-compatible inputs, open-drain diagnostic outputs (ST1/ST2), and embedded protection including overcurrent, short-circuit, thermal shutdown, overvoltage (65 V), reverse battery (–32 V), and open-load detection. It delivers 2.8 A nominal load current per channel at 24 V with R_ON = 125 mΩ (typ.) and supports parallel operation for higher current capability.

For engineers reviewing the BTS707NTMA1 datasheet, BTS707NTMA1 pinout, BTS707NTMA1 application, or BTS707NTMA1 equivalent, key selection considerations include its dual-channel high-side switching architecture, diagnostic feedback timing (e.g., td(ST OL3) = 200 µs), thermal resistance (R_thja = 37 K/W all channels active), undervoltage hysteresis (∆V_bb(under) = 0.4 V), and parallel-channel configuration requirements (wired-OR ST outputs, shared IN/OUT).

Technical Context

The BTS707NTMA1 integrates two independent PROFET high-side switches on a single monolithic die, each with dedicated ground pins (GND1/GND2), status outputs (ST1/ST2), and logic-level inputs (IN1/IN2). Its charge pump enables full functionality down to V_bb = 5.8 V without external boost circuitry.

Protection functions operate autonomously: short-circuit current limiting (IL(SCp) = 4–19 A depending on T_j), output clamping (V_ON(CL) = 59–75 V), thermal trip at 150 °C with 10 K hysteresis, and open-load detection triggered when V_OUT > 3 V in OFF-state. Diagnostic behavior follows a defined truth table with distinct ST pin states for normal, open-load, short-to-GND/V_bb, overtemperature, and undervoltage conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
Channel count	Dual independent high-side switches with separate GND, IN, OUT, ST pins per channel
R_ON (max)	250 mΩ per channel at T_j = 25 °C, V_bb = 12 V - determines conduction loss and thermal rise under 2.8 A load
V_bb operating range	5.8 V to 58 V - supports 12 V and 24 V automotive systems with undervoltage lockout at 2.7–4.7 V
Overvoltage protection	65 V clamp (V_bb(AZ)) - protects internal logic during load dump transients
Diagnostic response time	td(ST OL3) = 200 µs max - defines minimum detectable open-load duration before ST asserts high
Thermal resistance (all channels)	R_thja = 37 K/W on 50 mm × 50 mm FR4 PCB - sets maximum power dissipation limit (1.6 W at T_a = 85 °C)
ESD rating	1.0 kV HBM on IN/ST pins - ensures robustness during board handling and assembly

Pinout & Package

Package: PG-TO263-7-1 (TO-263-7 variant with exposed leadframe connected to V_bb pins); thermally enhanced surface-mount package with 7-pin layout and large copper area for V_bb connection.

Pin/Terminal	Circuit Role	Design Meaning
V_bb (pins 1,10,11,12,15,16,19,20)	Positive supply input	Common high-side rail connection; pins tied to internal leadframe for low-inductance, high-current path to both channels
IN1 (pin 3), IN2 (pin 7)	CMOS-compatible enable inputs	Logic-high (>2.5 V) activates respective channel; hysteresis ∆V_IN(T) = 0.5 V prevents noise-induced toggling
OUT1 (pins 17,18), OUT2 (pins 13,14)	Protected high-side power outputs	Switched V_bb to load; designed for max short-circuit current routing and inductive demagnetization energy handling
ST1 (pin 4), ST2 (pin 8)	Open-drain diagnostic outputs	Low = fault (short, overtemp, UV); high = OFF-state fault (open load) or normal OFF; requires external pull-up
GND1 (pin 2), GND2 (pin 6)	Ground references per channel	Isolated ground paths prevent crosstalk; essential for accurate current sensing and reverse-battery protection with RGND
N.C. (pins 5,9)	No-connect terminals	Not internally bonded; must remain unconnected to avoid parasitic coupling or mechanical stress

Key Features

Feature	Design Value
Fast inductive demagnetization	Output clamp voltage V_ON(CL) = 59–75 V enables rapid energy dissipation without external flyback diodes
Reverse battery protection	Supports –32 V with external 150 Ω resistor in GND path - critical for automotive battery disconnect scenarios
Parallel channel operation	IN/OUT pins can be wired in parallel; ST outputs require wired-OR configuration with single pull-up for consolidated fault reporting
Loss-of-ground detection	Monitors GND potential via internal comparators; asserts ST low if GND rises above VIN – VIN(T+) - prevents unintended turn-on
CMOS input compatibility	Input threshold V_IN(T+) = 1–2.5 V and I_IN(on) = 10–70 µA allow direct µC GPIO interface without level-shifting

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BTS708N1TMA1	Single-channel version with identical R_ON (125 mΩ), same protection set, but no ST2 or IN2; smaller footprint (PG-TO263-5)	Used where space constraints prohibit dual-channel layout or where channel independence is not required	Select when only one load needs controlled switching and PCB area is limited - reduces pin count and routing complexity
BTS724G	Quad-channel 3.5 A high-side switch with SPI interface, programmable current limit, and enhanced diagnostics (e.g., current readback)	Targets systems requiring digital configurability and multi-channel coordination, not analog GPIO control	Choose for next-generation designs needing remote configuration, precise current monitoring, or integration with CAN/FlexRay networks

Compared with BTS707NTMA1, BTS708N1TMA1 offers footprint reduction at the cost of channel count, while BTS724G trades simplicity and cost for digital controllability and richer telemetry - making BTS707NTMA1 optimal for cost-sensitive, dual-load analog-control applications with deterministic fault reporting.

FAQ

Can BTS707NTMA1 drive inductive loads without external flyback diodes?

Yes. The device features integrated output clamping with V_ON(CL) = 59–75 V, enabling safe demagnetization of inductive loads such as solenoids and relays. Energy is dissipated internally during switch-off, eliminating the need for external freewheeling diodes in most applications - though PCB layout must accommodate thermal limits under repeated inductive switching.

How does open-load detection work in OFF-state?

When IN is low and the load is disconnected, internal circuitry pulls OUT toward V_bb through a weak current source (~6 µA). If V_OUT rises above 2.4–4 V (T_j-dependent), the ST pin transitions high after 200 µs (td(ST OL3)), signaling an open-circuit condition. This occurs only in OFF-state and does not trigger during normal ON operation.

What is required to enable reverse battery protection?

A 150 Ω resistor must be placed in series with each GND pin (RGND1/RGND2) or a single 75 Ω resistor in the common GND path. This limits reverse current through the intrinsic body diode during –32 V battery reversal. Note that thermal protection is inactive during reverse operation, so power dissipation must be calculated using V_F ≈ 1.2 V and I_REV = 32 V / 150 Ω ≈ 213 mA.

Can both channels be operated in parallel for higher current capacity?

Yes - IN1/IN2 and OUT1/OUT2 can be directly paralleled, doubling nominal current capability to ~5.6 A. ST1 and ST2 must be wired as a wired-OR with a single pull-up resistor to report combined faults. Thermal derating applies: R_thja remains ~37 K/W, so total power dissipation must stay within 1.6 W at T_a = 85 °C to avoid thermal shutdown.
